The Tom Tancredo presidential campaign, 2008 for President of the United States began with the announcement of candidacy by the Congressman from Colorado on April 2, 2007. Since then, the campaign had garnered grassroots support and endorsements from conservative Republicans concerned about illegal immigration and border security. However, the candidate 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.
