Some Democrats complain that Republicans in recent decades have had the edge in House races because GOP state legislatures have been better at the gerrymandering game. Except that may not be true.
Some political experts believe there's an easier explanation, and perhaps a tougher one for Democrats to overcome: Voters supporting Republican House candidates, they say, are spread over more congressional districts than those who support Democrats. It's that simple. It's merely a matter of geography.
Voters were frustrated by a 2012 presidential race they called more negative than usual and more devoid of substantive discussion of issues, according to a survey released Thursday by the Pew Research Center.
And voters are pessimistic about the prospect of a more productive Congress, Pew found.
Two-thirds of registered voters surveyed after Election Day said they believe relations between Democrats and Republicans will stay the same or worsen over the coming year.
There has been no dearth of post-election Republican self-flagellation.
Louisiana Gov. Bobby Jindal, on the eve of heading out to a meeting of Republican governors in Las Vegas, warned the GOP to "stop being the stupid party." At the gathering Wednesday night, he leveled more harsh criticism at party presidential candidate Mitt Romney.
The Republican Governor's Association is meeting this week in Las Vegas. Republicans lost seats in the House, Senate and the presidential race. But the GOP gained one more state, North Carolina, to put the number of Republican governors at 30. The governors say there's nothing wrong with the party that a few changes around the margins won't fix.
If voters were surprised to watch TV networks call the election for President Obama over Republican Mitt Romney minutes after polls closed in California last week, perhaps it was because of earlier statements like these:
--"Romney has pretty much nailed down Florida."
--"I think in places like North Carolina, Virginia and Florida, we've already painted those red, we're not polling any of those states again."
