The 'Rats are complete scumbags, but they're not completely braindead. No way they would ever announce to the world, "We're giving up on the one state which would give us a reasonable chance of winning this election. Now we're down to miracle scenarios, but since we've kicked all religious people off this campaign, looks like we're fresh out of those too."
And pulling out of a scheduled appearance in such an important swing state as Florida - is tantamount to yelling "UNCLE!" into a megaphone.
