Sherrod Brown has made a successful political career out of being one person in Ohio, where he talks about support for Ohio jobs, and another when he is in Washington, where he votes for liberal job killing policies.
Some examples would be that he cast the deciding vote for Obamacare, and he has supported "card check", which would effectively eliminate the secret ballot when employees vote whether or not to form a union.
Make no mistake, Brown is a talented politician in that he has convinced many voters that he is a mainstream populist, while the rest of us know that he is rated as the most liberal in the Senate (tied with others). The campaign against him will no doubt attempt to educate Ohio voters as to how extreme Sherrod Brown really is. Josh Mandel just fired the first round.
