Heller was appointed to replace former Sen. John Ensign (R-Nev.) last year and has touted his Senate votes that broke with Republican ranks.

Heller and Berkley are fighting in a close race that could determine which party controls the Senate.

The Sun reported that despite Heller admitting his need for Democratic voters’ support, he hasn’t written off a victory in Nevada for the GOP nominee Mitt Romney.

“I think it’s going to be real close, but I think they can do it,” Heller said shortly after GOP running mate Paul RyanPaul Davis RyanGOP leaders to Trump: Leave Mueller alone Overnight Regulation: FTC to probe Facebook over user data | FDA takes step to regulating flavors in tobacco products | Congress may include background check measure in funding bill Judge rules FEC wrongly dismissed complaint against conservative group MORE delivered his final campaign speech in Reno. “I just chatted with Congressman Ryan, and he said it will be more difficult to win Nevada than Ohio but that they think they can win both.”
