I would have more respect for this if they brought each nominee up for a vote and then voted them down. It's the Senate's constitutional role to confirm or reject the president's nominees.
I agree. This whole issue could be avoided by all presidents from any party if the Senate were required to vote on a nominee within a certain timeframe after the president nominates a candidate - perhaps 90 days. It's really ridiculous that senators can arbitrarily refuse to vote on things when voting on things is what they are paid to do.
