The 2008 presidential campaign of Tom Tancredo, a Congressman from Colorado began on April 2, 2007 with a formal announcement. The campaign garnered grassroots support and endorsements from conservative Republicans concerned about illegal immigration and border security. However, Tancredo remained low in the polls and was criticized for his nativist campaign, which had been described as "single-issued." Tancredo stated that he probably would not win the nomination but hoped his campaign would bring forth more debate on his issue of concern, immigration. On December 20, 2007 Tancredo withdrew from the presidential race, and endorsed Mitt Romney.
