First of all, Clinton himself used the power of Recess Appointments 143 times during his Presidency. Did you call him a dictator?
Secondly...Under the Constitution's so-called "Recess Appointments Clause" (Article II, Section 2), the president has the power to temporarily fill any official "vacancy" without approval of the Senate when Congress is not in session. Anyone so appointed sits in office until the Senate votes on their confirmation—or until the Senate's next session expires. Check out the constitution some time...it's an amazing document you guys seem to want to change on a daily basis. There is a way around this...and it is not choosing to NOT have a U.N. Ambassador. Let Bolton's nomination go to the floor for an up and down vote. Simple as that. Tell your senators to vote no...then it will not be an issue. But, you know that Bolton has the 51+ votes to be confirmed and the Dems are using procedural issues to block a vote...so, this is what they get.
...and then there is this lovely little whoops!
"It's even worse for the administration to abuse the recess appointment power by making the appointment while Congress is in this five-week recess. It's a devious maneuver that evades the constitutional requirement of Senate consent and only further darkens the cloud over Mr. Bolton's credibility at the U.N."

"I have long since urged recess appointments to break log jams"

You guys are just mad because it clearly reminds you & your party that you are no longer in power.
