I don't care what early polls say. Nominating Grayson would make this race safe R.
Alan Grayson is a self-righteous blowhard that even liberals can't stand anymore. Patrick Murphy is the kind of candidate Democrats should be running across the country; he's a uniter who'll attract Democrats, independents, and yes even Republicans. Alan Grayson would alienate and turn off pretty much anybody who's not a bitterly partisan Democrat or a Bernie Sanders Tumblrina.
Grayson is a dreadful candidate but a big enough wave washes up a lot of junk on the shore. Just look at Florida's own governor for proof.
