Senate Majority Leader Harry Reid (D-Nev.) is up with the third television ad of his re-election campaign, still more than a year out from when voters go to the polls in 2010. The latest ad, titled “Right Direction,— focuses on alternative energy and how Reid “is leveraging his seniority to make Nevada the nation’s leader in renewable energy and clean jobs,— campaign manager Brandon Hall said in a statement.The ad comes on the heels of an introductory ad campaign that Reid launched two weeks ago that featured two spots touting Reid’s Nevada roots and his ability to use his clout in the Senate to help his home state. The campaign claimed they need to get an early start to reintroduce the senior Senator to the third of the state’s electorate that wasn’t living in Nevada when Reid was last up for re-election in 2004.Reid’s 2010 race is shaping up to be one of his toughest yet. He trails in the polls against two relatively unknown GOP candidates and has low approval ratings across the state. Nevada voters, hit hard by home foreclosures and a drop in construction and tourism revenue, are growing restless about the state of the economy.Reid has been emphasizing Nevada’s potential as a center for alternative energy generation, hoping that can help pull the state out of its economic doldrums. And thanks to a mammoth $8.7 million campaign war chest that the Senator had stockpiled through Sept. 30, he can afford to start pushing that narrative on television this far out from the election.
