There's a reason why U.S. Senators are usually such terrible Presidential candidates. It's because there is more testosterone in a typical kindergarten class than in the entire U.S. Senate.
But that aside, I still am not happy with this pick. And I think filibusters are beside the point, because one can't reasonably argue at this point that the president has avoided political controversy or weakness with this pick. Far from it. Therefore, imo, he'd have been better off picking a fight with the other side, rather than with conservatives. But, it's all water under the bridge now, and we'll just have to wait and see.
