On December 20, 2007 Tancredo withdrew from the presidential race, and endorsed Mitt Romney.

Brownback had first been elected to the Senate in a special election in 1996, previously having been a member of the U.S. House of Representatives. He was popular among social conservatives and positioned himself as a compassionate conservative, often using his Catholic faith to justify some of his policy positions. From the start of his announcement, media outlets noted that his candidacy was a long-shot and highly unlikely to succeed, and throughout the campaign, Brownback struggled with both fundraising and rising above single-digits in opinion polls.
