You only waste your vote if you don't vote, or if you vote for the same bunch and expect them to change.
Find you another party and vote!
Let the ones who keep getting suckered into putting these same two paternal twins back in, waste their votes once again.
Nothing is going to change until enough of us decide to bite the bullet and change it.
If the Republican Party is going to change it won't be done by those who just keep hoping,and voting for the lesser of two evils.
They won't change if they win because they won't have any reason to do so.
