Republican House Speaker John Boehner would win only 49 percent of the Republican vote if his re-election race were held today, according to an internal survey conducted by Gravis Marketing, results of which were obtained exclusively by The Daily Caller.

Boehner picked up 49 percent support in his re-election bid and registered a 30 percent “unfavorable” rating in the poll, which surveyed Republican voters in Ohio’s eighth congressional district that have voted in all four of the last Republican primaries in the state. The internal phone survey was based on a sample size of 2,275 high-propensity voters in the district.

Boehner faces tea party challenger J.D. Winteregg in Tuesday’s Republican primary, in which approximately 85,000 voters are expected to head to the polls. Winteregg, who has been endorsed by the Tea Party Leadership Fund, was recently fired from his job as an adjunct professor at Ohio’s Cedarville University for running a viral commercial parody accusing Boehner of “Electile Dysfunction.”

Winteregg joined Boehner’s 2010 Democratic opponent Justin Coussoule in an exclusive club: Boehner’s last two serious district challengers were both fired from their Ohio jobs during their campaigns.

Though more than $300,000 has been spent on Winteregg’s behalf in the campaign, Boehner has drastically outraised the tea party candidate and is inundating district voters with mailings and paid door-knocks ahead of Tuesday’s primary.
