Rob Portman? Are you kidding? I follow politics very closely, but cannot tell you one thing about Portman except that he’s a Republican Senator from Ohio. Period. I wouldn’t recognize him if he came to my door telling me to vote Republican.
The man has virtually zero name recognition, and unless he’s a Big Splash personality, he’s going to add nothing.
I’ve been noting the budding romance between Romney and Paul Ryan. That would be much more likely.
Portman is a generally good guy, but is sleep-inducing. Romney needs something more than that.
