Um that was actually fallout from Obama's negligence. They still haven't gotten pay back from Harry Reid but hopefully they will and soon....
Again, false. Obama appointed lots of judges; the Senate didn't confirm them. Most of Obama's term, while the Democrats had control of the Senate, judicial nominees could be "filibustered." Because of this, very few of Obama's judicial nominations were being approved -- Republicans were blocking them because Democrats rarely had 60 members in the Senate. Between Sen Franken being in a contested election, and not being seated until July, and Sen Kennedy's illness, as well as a variety of other changes, the Democrats only had a 60 vote majority for a very short time.
Sen. Reid got frustrated with the Republicans blocking judicial nominations and, in Nov 2013 (just short of 5 years after Obama took office) he used the "nuclear option" to get rid of judicial filibusters -- judicial nominees could finally be passed with 51 votes, Republicans could no longer block them. McConnell and other Republican warned Sen. Reid but Reid did it anyway -- and Democrats managed to get some of the backlog of Judicial nominees confirmed. Of course, then the problem was Democrats lost the Senate a year later.
In 2016, McConnell took full advantage of Reid's action and has moved to confirm as many of Trump's judicial nominees as possible. Additionally, McConnell himself used the nuclear option to get rid of filibusters against Supreme Court nominees (to push Gorsuch's nomination through faster). Reid's karma has been paid back -- though it will be interesting to see what "karma" McConnell has now collected. As I mentioned earlier, if Trump gets another nominee through, it would not surprise me if Democrats "pack" the court -- and if they control both the Presidency and the Senate, Republicans (due to McConnell) will not be able to stop them.
