As ever, I couldn't resist putting this up:

Mitt Romney spent yesterday morning barnstorming the small farming communities of Eastern Iowa, holding a series of "Ask Mitt Anything" events and urging his supporters to turn out for the straw poll in Ames on Saturday.

[...]

"How many counties are in Massachusetts?" she asked.

"Thirteen," he said. A few feet away, an aide shook his head and said, "Ten."

Not being from Massachusetts, or even New England, I wouldn't have a clue how many counties there are in the Bay State. But then again, I didn't used to be Governor up there.

For the record, Wikipedia says 14. So it seems that neither Mitt nor his aide are too clued up on this one.
