Is this a smart tactic for Gingrich?

As I mentioned the other day, last week didn't seem like a very good week for Newt Gingrich, and mainly because the week was about two things: his proclivity to keep coming up with stupid ideas, and his longstanding record as a serially unfaithful husband.

So is this really the best time for him to be reminding people of sexual improprieties?

[Herman Cain], who left the race before the first nominating contests after facing accusations of unwanted sexual advances, suggested the two have both undergone intense scrutiny.

"I know that Speaker Gingrich is running for president and going through this sausage grinder," Cain said. "I know what this sausage grinder is all about."

What's the message here? Philanderers for Gingrich?

In a week where he's already taking heavy fire for his own sexual peccadilloes, does Gingrich really need this?
