Democrats' once-reliable Baby Boomer bloc leans conservative

The Dallas Morning News reports:

This is turning into a tough election year for Democrats, and most of the reasons are familiar: The economy is stalled, President Obama's popularity is sagging and voters are in an anti-incumbent mood. There's an "enthusiasm gap," too. Republican voters are fired up and ready to vote, while liberals are dispirited.

Now add one more factor: a new generation gap. Voters over the age of 50 are leaning increasingly Republican, according to recent polling – and that includes members of the giant baby boom generation between 50 and 64.
