Who is "they"?
I've been hearing this "vote for the lesser of two evils" crap for decades.
What has it gotten us?
Evil.
Count me out.
And don't blame me if evil (whether lesser or greater) gets elected.
Blame the people who voted for evil. Especially blame the people who voted for evil in the primaries ... and blame the party hacks who gave institutional support to evil.
If you have to "hold your nose" ... you're voting for evil.
Third Party - Better to go outside the party than to reward them for going down the toilet with McCain.
