Nixon's campaign hit back Thursday, launching a television ad that brings up an attack that Spence's opponents have used frequently over the course of the race: That a bank whose board Spence sat on took TARP funds -- and hasn't paid them back. "Now Spence is spending millions of dollars to run for governor," the narrator says. "Don't you think Dave Spence's bank should say us back before he runs for office?" The Democratic Governor's Association has also invested heavily in the race. Missouri leans Republican, but Nixon remains favored in the governor's race.
