It’s not a mistake. Reelecting Mitch was a mistake.
Imagine Alison Lundergan-Grimes in his place?
Bevin ought to have been written in. But it appears Kentucky is a blue state in a de facto sense.
Can we convict an illegal alien of treason?
The problem arose out of the GOP winning the senate, and Mitch, as majority leader, announced that he would move Kirk-Menendez forward.
Kirk-Menendez began in Dec of 2013 and was debated a few months into 2014, before it died.
Kirk-Menendez was probably pertinent back then(2013-2014), but by Jan of 2015 it was irrelevant because the end of negotiations were close at hand.
So the general consensus was that Mitch was politicizing the issue, which scared off several dem allies.
Then the small group of senators traveled to Israel to meet with Mossad, who also opposed Kirk-Menendez, which prompted McCain, Graham, and Angus Winn to drop their support for Kirk-Menendez, and fall in behind Corker's bill. Then the Brit Prime Minister came out against Kirk Menendez, but McConnell kept pushing it, undoubtedly for political reasons.
Then, after Corker's bill had replaced Kirk-Menendez, Mitch allowed amendments to be thrown up only for political reasons.
If the GOP continues to try to politicize it(after negotiations are over), it will fail.
