It's February 2011 folks. There's still too much to do before you announce your candidacy and thus restrict yourself in some of the tv appearances and other things one does at this stage in the race. That's why nobody smart is announcing yet that they are running, Sarah included.
I'm no Romney supporter but bashing him over this is a little childish. There's a reason none of the legit contenders have declared yet and so they're all playing this "haven't decided yet" game and lying through their teeth about it.
If you're NOT planning on getting in at this point, they probably are sitting out. But if you ARE planning to get it, now is not the time to make it official.
WTF? (Except Pissant).
