Pretty much everybody has weighed in on the saga of U.S. Sen. John Ensign. Here’s a roundup of a few interesting pieces on the case:

• Conservative blogger Michelle Malkin calls Ensign a dog, and says never trust a man in politics whose hair is prettier than his wife’s. Good advice! She then goes on to say John Conyers is worse.
• NPR’s Political Junkie Ken Rudin wrestles with how much of a politician’s private life should be public, and concludes that Ensign’s public morality adds another dimension to the story. (The Review-Journal’s Molly Ball and Steve Teatreault are name-checked therein!)
• DailyKos documents a little Ensign hypocrisy, and notes the alleged blackmail. (Question: There will be charges filed on that, right? We’re not going to let an alleged blackmailer of a U.S. senator go unpunished, right?)
• Politics Daily wonders if this “garden variety” fling with an aide even qualifies as a scandal.
• Ditto for Wonkette, which notes Ensign was separated from his wife at the time. (Not exactly; the separation happened after the affair began, and perhaps because of it, but who are we to quibble with Wonkette?)
• Another theory on Gawker: Ensign was forced to come forward after the Hamptons had trouble paying the mortgage on their $1.2 million Summerlin home and thus asked the senator for more hush money.
• And, of course, the R-J editorial: Unlike, say, Bill Clinton, Ensign can do whatever he wants, because he agrees with the newspaper on the free market. Don’t ever change, senator! (Alas, apparently even Ensign doesn’t read the R-J. He resigned his leadership post the same day the editorial was published.)
