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. Texas utilizes an open primary system. Voters do not have to register with a party in advance in order to participate in that party's primary. The voter must sign a pledge stating the following (the language below is taken directly from state statutes)[1]
| “ | The following pledge shall be placed on the primary election ballot above the listing of candidates' names: 'I am a (insert appropriate political party) and understand that I am ineligible to vote or participate in another political party's primary election or convention during this voting year.'[2] | ” |
