Under ousted chief executive Rick Wagoner, General Motors and its political action committee gave twice as much to Republicans as they did to Democrats. From 2000, when Wagoner took over the Detroit-based auto-maker, through the end of last year, GM and its PAC contributed $1.7 million to Republican candidates and committees, compared only $815,000 to Democratic ones, according to a POLITICO analysis of Federal Election Commission and Internal Revenue Service records.
