Someone might...

First, Ann (mind you, here she is lashing out at Republicans who are criticizing poor Willard).

Ann might think about growing a thicker skin if she wants to be the First Lady.  It's not like she's had to hear accusations that her husband is a:

* Communist
* Marxist
* Muslim
* Fascist
* Nazi
* Kenyan
* A non-citizen...

Second, it would seem that on the Univision appearance, Mittens didn't like the way the introduction went initially, and asked them to redo it or he wouldn't continue.  Also, he allegedly threatened to 'reschedule', if the audience wasn't filled with activists...instead of students, as was initially agreed upon.  I guess they couldn't get enough students interested.

Grant you, the second one hasn't necessarily made the rounds in the main stream media, as a lot is hearsay.  But if it did happen, I'm guessing the reason he didn't like the introduction is because will all that bronzer he was wearing, they may have introduced him as John Boehner.
