well if there’s no need for principle then why do we need to remove Harry Reid, or to stop Obama’s agenda?
There is a place for principle.
But it doesn't belong in the voting booth if it leads to self-destructive voting. The voting booth is a place to cast a vote coldly calculated to advance a principled agenda as best as possible under the circumstances. It is not a place to throw a principled temper tantrum that leaves you feeling better about yourself but is really just pissing in the wind.
