Primary elections—in which registered voters select a candidate whom they believe should run on the party's ticket in the general election—can reflect internal conflict over the direction of a party.
Heading into the 2018 election, the Republican Party's legislative record during Donald Trump’s presidency figured into several Republican primaries. This record included the passage of major tax legislation in December 2017 and the confirmation of federal judges. It also included a $1.3 trillion omnibus spending bill in March 2018, which Trump opposed, and unsuccessful efforts to repeal and replace the Affordable Care Act.[3][4]
Trump, himself, also played a role in Republican primaries. His approval rating reached 90% in June among self-described Republicans, according to a Gallup survey.[5] Many Republican candidates campaigned on their support for Trump, and negative ads accusing opponents of criticizing the president were common.[6][7][8] A May report found Trump's name or image had appeared in 37% of all Republican campaign ads at that point in 2018.[9]
This page focuses on the Republican primaries that took place in Colorado on June 26, 2018. In addition, the page provides context for understanding the state party apparatus.
Ballot access requirements
Candidates may qualify for the primary ballot in Colorado in two ways: nomination by petition or by assembly. To be nominated by petition, candidates for the U.S. House must collect either 1,000 signatures or a number of signatures equal to 30 percent of the votes cast in the district in the most recent party primary election for the same office, whichever is less. Candidates for governor or the U.S. Senate must collect 1,500 signatures per congressional district. To be nominated by assembly, a candidate must receive 30 percent of votes cast by assembly delegates. If no candidate receives 30 percent, a second vote is taken. If no candidate receives 30 percent at the second vote, the top two vote-getters are nominated. Candidates can choose to be nominated both ways, but a candidate who attempts to be nominated by assembly and fails to receive at least 10 percent of the delegates' votes may not be nominated by petition.[10]
Unaffiliated voters in Colorado primaries
The June 26, 2018, primaries were the first chance that Colorado voters unaffiliated with either major party had to participate in partisan primaries. The state's 1.1 million unaffiliated voters received mail-in ballots from their county clerks and were not able to opt out of receiving a ballot. If a voter did not request a ballot from one party, she or he received ballots for both parties. Voters could only complete a ballot for one party's primary. If the voter completed both party ballots, the ballots were invalidated.
County officials recommended that voters mail their ballots in by June 16. If voters chose to drop their ballots off at their county election offices, they had until 7:00 PM MT on June 26.[11]
This change in the voting system came from Proposition 108, a 2016 initiated state statute approved by 53.3 percent of voters. Prior to the passage of Proposition 108, Colorado utilized a closed primary system where only voters registered with a political party could participate. Unaffiliated voters were able to affiliate with one of the parties on election day if they chose.

Voter information
How the primary works
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election.
Colorado utilizes a semi-closed primary system. According to Section 1-7-201 of the Colorado Revised Statutes, "An eligible unaffiliated elector, including a preregistrant who is eligible under section 1-2-101 (2)(c), is entitled to vote in the primary election of a major political party without affiliating with that political party."[16][17]
For information about which offices are nominated via primary election, see this article.
Poll times
In Colorado, polls are open from 7:00 a.m. to 7:00 p.m. local time for those who choose to vote in person rather than by mail. An individual who is in line at the time polls close must be allowed to vote.[18][19]
Registration requirements
- Check your voter registration status here.
In Colorado, an individual can pre-register to vote if they are at least 15 years old. Voters must be at least 18 years old to vote in any election. A voter must be a citizen of the United States and have established residence in Colorado to vote.[20]
Colorado voters can register to vote through Election Day. However, in order to automatically receive a absentee/mail-in ballot, a voter must register online, through the mail, at a voter registration agency, or driver's license examination facility at least eight days prior to Election Day. A voter that registers through a voter registration drive must submit their application no later than 22 days before the election to automatically receive an absentee/mail-in ballot. A voter can register online or submit a form in person or by fax, email, or mail.[20][21][22]

Same-day registration
- See also: Same-day voter registration
Colorado allows same-day voter registration for individuals who vote in person.
Residency requirements
Colorado law requires 22 days of residency in the state before a person may vote.[21]
Verification of citizenship
Colorado does not require proof of citizenship for voter registration. An individual applying to register to vote must attest that they are a U.S. citizen under penalty of perjury.
All 49 states with voter registration systems require applicants to declare that they are U.S. citizens in order to register to vote in state and federal elections, under penalty of perjury or other punishment.[23] Seven states — Alabama, Arizona, Georgia, Kansas, Louisiana, New Hampshire, and Wyoming — have laws requiring verification of citizenship at the time of voter registration, whether in effect or not. One state, Ohio, requires proof of citizenship only when registering to vote at a Bureau of Motor Vehicles facility. In three states — California, Maryland, and Vermont — at least one local jurisdiction allows noncitizens to vote in some local elections. Noncitizens registering to vote in those elections must complete a voter registration application provided by the local jurisdiction and are not eligible to register as state or federal voters.
Verifying your registration
The site Go Vote Colorado, run by the Colorado Secretary of State office, allows residents to check their voter registration status online.
Voter ID requirements
Colorado requires voters to present non-photo identification when voting in person. If voting by mail for the first, a voter may also need to return a photocopy of his or her identification with their mail-in ballot. Click here for more information.

Early and absentee voting
Colorado conducts what are commonly referred to as all-mail elections. In Colorado, voting is conducted primarily, although not necessarily exclusively, by mail. Election officials automatically distribute mail-in ballots to active electors starting 18 to 22 days before an election. Colorado law requires county clerks to operate polling locations (Voter Service and Polling Centers, or VSPCs) starting 15 days before an election and continuing through Election Day, excluding Sundays. At these locations, eligible voters can do any of the following:[26]
- void their mail-in ballots to vote in person,
- register to vote,
- update existing voter registration records,
- obtain mail-in ballots, or
- vote in person via paper ballots or accessible voting devices.

- ↑ Under federal law, the national mail voter registration application (a version of which is in use in all states with voter registration systems) requires applicants to indicate that they are U.S. citizens in order to complete an application to vote in state or federal elections, but does not require voters to provide documentary proof of citizenship. According to the U.S. Department of Justice, the application "may require only the minimum amount of information necessary to prevent duplicate voter registrations and permit State officials both to determine the eligibility of the applicant to vote and to administer the voting process."
