Earlier this week, we ran an item about how one of college football's biggest rivalries -- Ohio State-Michigan -- became an angle in the presidential campaign. Democrats placed an ad in the Ohio State student paper to spotlight Mitt Romney's allegiance to the archrival Wolverines.

Now there's a connection between America's most popular high school football team, albeit fictional, and Romney.

In an exclusive story, The Hollywood Reporter reveals Peter Berg, writer and director of Friday Night Lights, sent a letter to the Romney campaign to complain that the GOP candidate has co-opted one of the show's signature phrases.

The line in question is "Clear Eyes, Full Hearts, Can't Lose."

The Reporter quotes from the letter it obtained:

"Your politics and campaign are clearly not aligned with the themes we portrayed in our series. The only relevant comparison that I see between your campaign and Friday Night Lights is in the character of Buddy Garrity -- who turned his back on American car manufacturers selling imported cars from Japan."

In addition to Romney's use of the phrase in campaign speeches, it also appears on his Facebook page.

The Hollywood Reporter notes that Berg is "an outspoken Barack Obama supporter" and that his letter asserts Romney's use "falsely and inappropriately associates Friday Night Lights with the Romney/Ryan campaign."
