What have the Democrats to offer? Other than unemployment and the so called "social issues"?
Not hating the poor, minorities, and gays, not wanting to go to war at every provocation, and generally not acting nearly as dickish as the other side.
Yes, my impression is also that the only thing the Democrats have to offer is that they aren't Republicans.
Many people vote for the lesser of two evils so this is enough. There are lots of third parties with good platforms, but people need a choice that can actually win, so voting for Democrats simply to not have horrible Republicans in office is a wise choice.
