Farm bill

Yea3.png On February 4, 2014, the Democratic controlled Senate approved the Federal Agriculture Reform and Risk Management Act of 2013, H.R. 2642, also known as the Farm Bill.[9] It passed the Senate with a vote of 68-32. The nearly 1,000-page bill reformed and continued various programs of the Department of Agriculture through 2018. The $1 trillion bill expanded crop insurance for farmers by $7 billion over the next decade and created new subsidies for rice and peanut growers that will kick in if or when prices drop; however, cuts to the food stamp program cut an average of $90 per month for 1.7 million people in 15 states.[10] Udall joined with 46 other Democratic senators in favor of the bill.

2014 Budget

Yea3.png On January 16, 2014, the Democratic-controlled Senate approved H.R. 3547, a $1.1 trillion spending bill to fund the government through September 30, 2014.[11][12] The Senate voted 72-26 for the 1,582 page bill, with 17 Republicans and 55 Democrats voting in favor of the bill.[12] The omnibus package included 12 annual spending bills to fund federal operations.[13] It included a 1 percent increase in the paychecks of federal workers and military personnel, a $1 billion increase in Head Start funding for early childhood education, reduced funding to the Internal Revenue Service and the Environmental Protection Agency and left the Affordable Care Act without any drastic cuts. Udall voted with the Democratic Party in favor of the bill.[11][12]

Government shutdown

See also: United States budget debate, 2013

Yea3.png During the shutdown in October 2013, the Senate rejected, down party lines, every House-originated bill that stripped the budget of funding for the Affordable Care Act. A deal was reached late on October 16, 2013, just hours before the debt ceiling deadline. The bill to reopen the government, H.R. 2775, lifted the $16.7 trillion debt limit and funded the government through January 15, 2014. Federal employees also received retroactive pay for the shutdown period. The only concession made by Senate Democrats was to require income verification for Obamacare subsidies.[14] The final vote on H.R. 2775 was 81-18, with all 18 votes against the bill from Republican members. Udall voted with the Democratic Party for the bill.[15]

No Budget, No Pay Act of 2013

Yea3.png Udall voted for H.R.325 -- No Budget, No Pay Act of 2013. The bill passed the Senate on January 31, 2013, with a vote of 64 - 34. The purpose of the bill was to temporarily suspend the debt ceiling and withhold the pay of members of Congress until a budget could be passed. The vote largely followed party lines with Democrats overwhelmingly supporting it and many Republicans in opposition to the bill.[16]


Mexico-U.S. border

Nay3.png Udall voted against Senate Amendment 1197 -- Requires the Completion of the Fence Along the United States-Mexico Border. The amendment was rejected by the Senate on June 18, 2013, with a vote of 39 - 54. The purpose of the amendment was to require the completion of 350 miles of fence described in the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 before registered provisional immigrant status may be granted. It would also require 700 miles of fence be completed before the status of registered provisional immigrants may be changed to permanent resident status. The vote followed party lines.[17]

Social issues

Violence Against Women (2013)

Yea3.png Udall voted for S.47 -- Violence Against Women Reauthorization Act of 2013. The bill was passed by the Senate on February 12, 2013, with a vote of 78 - 22. The purpose of the bill was to combat violence against women, from domestic violence to international trafficking in persons. All 22 dissenting votes were cast by Republicans.[18]

Previous congressional sessions

Fiscal Cliff

Yea3.png Udall voted for the fiscal cliff compromise bill, which made permanent most of the Bush tax cuts originally passed in 2001 and 2003 while also raising tax rates on the highest income levels. The bill was passed in the Senate by an 89 - 8 vote on January 1, 2013.[19]

Campaign themes


Udall's campaign website listed the following issues:[22]

  • Economic Opportunity & Building a Better Life: "Colorado has added more than 214,000 jobs since the recession, yet there are too many Colorado families that are still struggling to make ends meet. Mark knows that our economy is more than just statistics and numbers — it’s about creating the opportunity for families to work hard and build a better life."
  • Creating Good-Paying Colorado Jobs: "A recognized expert on energy issues, Mark’s leadership has helped make Colorado a model for the nation on smart energy policy. From efficiency and conservation, to wind, solar and other renewables, to the responsible development of clean burning natural gas, Colorado’s bountiful supply of energy doesn’t just power our homes and businesses, it drives our economy, creates good-paying jobs, and makes our country more secure."
  • Fighting For Our Rights & Values: "Our veterans put their lives on the line to protect us and for that we owe them the best health care this country has to offer. Mark works tirelessly to ensure all Colorado veterans are treated with the dignity and respect that they are owed. He successfully forced the VA to cut red tape so veterans don’t have to travel long distances for life-saving surgeries and has fought to reduce needless paperwork and redundant processes. To ensure our servicemen and women are cared for, Mark has also pressed the military to address post traumatic stress and fatigue stemming from multiple deployments."
  • Protecting Colorado’s Way of Life: "Mark works tirelessly to do right by Colorado, come hell or high water. And Colorado has seen both over the past year. He fought to get Colorado $770 million in emergency assistance to rebuild our communities, and repair our roads and bridges after last year’s historic flooding. And after forcing the Obama administration to give the Forest Service the modern tankers they needed to better fight Colorado wildfires, Mark is now leading the charge to simplify wildfire recovery by ensuring the government approaches them as they do hurricanes and tornados."
