We still have an electoral system.
So, no, all our votes won't be needed.
If we're going to vote pragmatically anyway, then why not try and kill two birds with one vote? Everyone in Red or "Purple" states holds their noses and votes Romney to keep Obama from getting another term. Everyone in Blue states votes Green Party to split the liberal vote.
Win, win.
If you truly believe that another four years of Obama will send this country into a communist/socialist tailspin then you might want to identify a battleground state that you and 10,000 of your closest friends can move to in time to vote there legally.
Yes, I LIKE your strategy!
