Breaking from his 2001 and 2003 votes, McCain supported the Bush tax cut extension in May 2006, saying not to do so would amount to a tax increase. Working with Democratic Senator Ted Kennedy, McCain was a strong proponent of comprehensive immigration reform, which would involve legalization, guest worker programs, and border enforcement components. The Secure America and Orderly Immigration Act was never voted on in 2005, while the Comprehensive Immigration Reform Act of 2006 passed the Senate in May 2006 but failed in the House. In June 2007, President Bush, McCain, and others made the strongest push yet for such a bill, the Comprehensive Immigration Reform Act of 2007, but it aroused intense grassroots opposition among talk radio listeners and others, some of whom furiously characterized the proposal as an "amnesty" program, and the bill twice failed to gain cloture in the Senate.
