Here's Cory Booker on The Rachel Maddow Show last night:

After hearing President Obama explain his position on Romney's business record earlier Monday, it became clear "he was focusing in on his job creation record," the New Jersey Democrat said in anevening interview, and "to me I think that's fair game."

Now that Booker is a company man again, I wonder if there's room under that big Democratic tent for him, and if his reputation can withstand the attacks he's suffered from the left.
