Michele Bachmann in Iowa

A new advertisement supporting Republican presidential candidate Michele Bachmann compares the congresswoman's longshot candidacy to Denver Broncos quarterback Tim Tebow's ascension in the NFL.

The ad begins with a shot of Tebow pointing two fingers to the sky and tries to create natural comparisons between Tebow and Bachmann ahead of the Iowa caucus on Tuesday.

The narrator says: The establishment sports guys just love to hate Tim Tebow. He's not smart enough, his mechanics are no good, he's not accurate enough. Still he just keeps winning. Maybe they're so invested in his failure because he makes them all feel guilty. He doesn't drink, smoke, cuss or even kick his opponents when they're on the ground. He has no baggage and, oh yeah, he's a born-again Christian. Well, the same could be said of Michele Bachmann. No baggage, Christian and, like Tebow, she just keeps fighting and she just keeps winning votes.

The advertisement -- paid for by the No Compromise PAC - isn't the first time a comparison has been made between a Republican primary candidate and Tebow. In December, Texas Gov. Rick Perry invoked the quarterback.

There are a lot of folks that said Tim Tebow wasn't going to be a very good NFL quarterback, Perry said. There are people that stood up and said well, he doesn't have the right throwing mechanisms, or he doesn't -- you know, he is not playing the game right. You know, he won two national championships, and that looked pretty good.

We're the national champions in job creation back in Texas. But am I ready for the next level? Let me tell you -- I hope I am the Tim Tebow of the Iowa caucuses.

Both Bachmann and Perry are considered major longshots to fare well in the Iowa caucus. Mitt Romney, Rick Santorum, and Ron Paul are all expected to poll better.

Even if Bachmann and Perry perform like Tebow - it wouldn't necessarily be a good thing. Tebow at one point guided the Broncos to six straight wins, but has struggled recently during a three-game losing streak. The Broncos managed to still make the playoffs, but face a tough wildcard weekend game against the Pittsburgh Steelers.
