I will vote R as long as there is nothing better, but I am not happy with the political, you pet mine and I'll pet your's, B.S.
I do the same, mostly, though I'm not against self-destruction if it means nailing an enemy.
McCain is a great example. I'd have no problem voting for a liberal dem just to punish him. Such joy is well worth the sacrifice, however counter-productive.
I mainly live for spite, one could say.
