Mitt Romney spokesman Richard Grennell has resigned. He was under assault from the left for his weird Twitter attacks on women. But he was getting a lot of flack from the right, too:

The foreign policy spokesman came under fire from social conservatives for being openly gay, as well as from Democrats for some crude tweets about female politicians.

Grennell's statement concludes:

I want to thank Governor Romney for his belief in me and my abilities and his clear message to me that being openly gay was a non-issue for him and his team.
