You can try to dodge it all you want, but those corrupt and bigoted Southern politicians were all Democrats. They made no bones about it, either. To a very large degree, if you go to any level of government where corruption is rampant, you'll find the government has been ran by Democrats. This isn't limited to the South either, unless you try to claim that Chicago is a southern city. Or Washington DC. Or Philly. Or New Jersey.
