Update: Hopefully the chart is more readable now
A few months back, Bill Maher quipped that the Democratic Party had moved to the right and the Right had moved into a mental hospital. I don’t know about the mental hospital part, but according the Gallup the Democratic party has definitely moved to the right.
Democrats became slightly less opposed to government regulation, though this is hard to judge as a strictly liberal/conservative divide in the wake of the financial crisis. Democrats also became less likely to be pro-choice.
On the other five issues polled, however, democrats have become more conservative. Union support among democrats seems to be particularly hard hit.
