In the party’s U.S. Senate seat race, Rep. Martin Heinrich was the top vote getter at Saturday’s convention with 55 percent of the statewide vote.

While Heinrich remains the frontrunner in the Senate campaign, State Auditor Hector Balderas, with 45 percent of the delegate vote, whittled away much of the lead with a better showing than many in the party anticipated before the convention.

Public Opinion Strategies partner Glen Bolger conducted the poll less than a week after Lt. Gov. John Sanchez’s Feb. 9 announcement that he was dropping out of the race. His decision left conservative businessman Greg Sowards as Wilson’s only GOP challenger.
In the poll, Wilson led Sowards 81 percent to 10 percent.

In the general election it should definitely be a race between Wilson and Heinrich. Heinrich's only chance, if he has one at all, is that he polls well with Hispanics, which is evident in his large lead over Balderas.

Beating Heather will be a formidable task. He's the only Dem that even has a snowball's chance. It will be very difficult for NM to hang on to the Dem seat being vacated. We're working on it, but just sayin'.
