The most likely answer is a tad bit of hyperbole. No?
Show us a couple of known liberals who have announced
their support for Romney so I can stay home on election
day to help re-elect Obama.
Why should I keep up with what liberals are saying about him, or anybody? That's not any better than news gossip about celebrities.
Take a look at the things he's done: Romneycare, implementing homosexual marriage, judicial appointments, implementing weapons bans. And that's only what my admittedly cursory knowledge on the man's actions reveals: I'm certain there's much more than that. (In fact, you could ask the people from his state, if you know where to find that ping list or message board.)
