You are way off the mark, Jackie.
The voters had negative impressions of Republicans and positive ones of the Democrats because those are the impressions that the liberal media gave them.
Once upon a time they tried to hide their bias or pretend it wasn't there, but they are fairly blatant about it today.
It is not just the news and opinion media: nearly every television show and movie promotes the idea that evil white heterosexual Republican men are responsible for the world's ills. Just the other night I got disgusted by a Law and Order, switched to a CSI which was just as bad, then finally a movie before I gave up and turned the set off.
We cannot let the left own nearly all the media. Fox News is not enough!
