To everyone who is on a tear about “voting against the incumbents”, please stop for a moment and think about what that really means:
1. you will be voting for the Republicans to take over congress.
2. you will be voting against Obama for president if you vote “independent”
Just do the math. Since the Democrats have a majority among the incumbents, you are in effect voting Republican. Is that really what you want to do?
One thing is to vote against the incumbents in a PRIMARY (nominational) election, but it is something different to vote against the incumbents in the GENERAL (real) election.
