What did you guys think "be a check on a Clinton Presidency" means? This is a winning message for Senate Republicans.
This goes beyond being a "check". The Senate is supposed to confirm the president's nominee unless there's actually a good reason not to. It's shameful to block nominees simply for partisan reasons.
No, the Senate has an equal say as the president. Both sides have to agree, or the candidate will not be confirmed. Nowhere does it say that the Senate has to find a non-ideological reason to reject a nominee.
