A Tester spokesman said in a statement Tuesday that the Senator looks forward to beginning an honest debate following the June 5, 2012, primary. Not all Montana Democrats are waiting to pounce: The state party released a scathing statement regarding Rehberg just an hour after his plans were reported.
Rehberg lost his first Senate bid in 1996 to Democratic Sen. Max Baucus. Since Rehberg was first elected to the House in 2000, he has never won with less than 59 percent of the vote.
Although Montana leans Republican, it has two Democratic Senators and a Democratic governor, and Barack Obama lost there by just 3 percentage points in the 2008 presidential election.
According to financial reports due Monday, Tester and Rehberg are even in cash on hand. Tester reported having $562,000 in the bank as of Jan. 1, while Rehberg had $553,000.
