Funny how that works both ways huh finny .
Saying that a vote for Romney is a vote for government tyranny is a statement of fact based on Romney's record, though voting for tyranny understandably won't be most voters' intent -- most will intend to vote "against" Obama.
Saying that not to vote for Romney "is the same as voting for Obama," on the other hand, is a flat-out material falsehood meant to demonize those who refuse to vote for Romney. There's only one way to vote for Obama, and that's to mark his name on the ballot.
Just as there's only one way to vote for government tyranny -- and that is to mark a statist's name on the ballot. Both Obama and Romney are demonstrated statists, so a vote for either one is a vote for government tyranny.
