Not quite in the same league as not being sure O is a Christian, was born American, isn't a Marxist, or whatever

Hillary not sure Bernie is a Democrat

Really?

I'll answer that: No, he's not.

He's an Independent and has always run as such.

But he caucuses with the Democrats and is a legitimate candidate for the Democratic nomination.

The media are cooperating with the sleazy insinuation aimed at really stupid voters that there is something fishy here.
