The Obama and Romney presidential campaigns don’t agree on much, but they joined forces to complain in advance about possible follow-up questions from CNN’s Candy Crowley, the moderator for Tuesday night’s town hall-style presidential debate.

It seems neither campaign is looking for Ms. Crowley, a veteran political journalist, to press their candidates with tough follow-ups to whatever questions are put forth by the audience of undecided and persuadable voters at Hofstra University in Hempstead, N.Y.

The campaigns’ attorneys, Ben Ginsburg for Republican Mitt Romney and Bob Bauer for President Barack Obama, jointly wrote a letter with their concerns addressed to the Commission on Presidential Debates and gave it to the commission last week when all parties were present for the vice-presidential debate.
