"Useful idiot" is a label for those who support socialists, not for those who refuse to do so.
You're confused.
The historical reference fits Romney Republican "conservatives" perfectly though.
I know that there may only be 50 or so people that vote for you (most of which are here), but that's 50 votes that could go to canceling out the presidency of the most socialist (let's call him a Marxist), most anti-American, most pro-muzzie, most pro-death, most anti-free enterprise, most divisive, most destructive, most anti-everything we love president ever.
To those 50 or so who vote for you......
Shame on them, and shame on you.
