Montana Democratic Senator Jon Tester won reelection Wednesday, beating Republican Danny Rehberg in one of the tightest Senate races of the election. No stranger to close calls—he won by a mere 3,562 votes in 2006—Tester remained confident throughout the mostly tied race that he would pull ahead. “Thank you for fighting with me—for Montana values,” he told supporters. The defiant senator became a major target for the Republican party—hoping to take over the Senate. More than 100,000 campaign ads ran on Montana television during the campaign—in what some are calling a “perverse media marathon” that incurred costs close to $30 million. Tester's win dashed GOP hopes of regaining control of the Senate.
