we are 606 days away from election day, go get ready. ohio senator sherrod brown just took himself out of the running. could it be because former vice president joe biden is about to jump in? there's something about harry so let's break it down with harry enten. so, was sherrod brown tipped off by the joe biden people to get out? >> i don't know if he was tipped off by the joe biden people, but certainly there was some belief biden getting in would hurt brown's chances. if you look at where sherrod was in the polls, he was only at 1%. >> he wasn't in yet. >> he wasn't in yet. he would have gotten in but it would have been difficult with so many candidates running to get that name recognition up, to get the press that was necessary, especially if biden were to jump in. there's only so much press attention. but i think that brown getting out, he was one of the first that i really thought had a real shot, a real dark horse of winning the knox nation. he running third.
