GOP Congressman Tom Tancredo has a lot of catching up to do. The first Rasmussen Reports national telephone survey gauging support for Tancredo's long-shot presidential candidacy shows him trailing New York Senator Hillary Clinton by thirteen percentage points. He also trails Illinois Senator Barack Obama by seventeen.

The poll shows Clinton with a 50% to 37% advantage while Obama tops Tancredo 48% to 31%. Other long-shot Republicans have proved more competitive in match-ups with Clinton than Tancredo. The former First Lady has never managed double-digit leads in any Rasmussen Reports match-up between her and Sam Brownback, Mike Huckabee, or Chuck Hagel. Only Ron Paul fares worse against Clinton than Tancredo, trailing her 34% to 49% in a July survey.

Even so, the Colorado Republican—who has made illegal immigration a staple issue of his campaign—would be competitive against Senator Clinton in a general election held today if men alone were voting. Among that group, they're tied 44% to 44%. Tancredo still trails among male voters by double digits in the Obama match-up.

Most voters (54%) don't know Tom Tancredo well enough to give an opinion of him. Only 20% report a favorable view, while 26% have an unfavorable view.

Hillary Clinton is viewed favorably by 47%, unfavorably by 50%. Barack Obama, now a distant second to Clinton in the Democratic nomination race, is viewed favorably by 50%, unfavorably by 43%.
