Jeff Flake thinks John Kasich, Ben Sasse or some governors should challenge Pres Trump in 2020 but not himself! Flake isn’t running for reelection not because of the electorate or republicans moving away from conservative values, he isn’t running, nor has the balls to run against Trump (for now), because he DOES NOT HAVE the values he claims is missing from the party.
Flake sides with the democrats on many issues from gun control to the Iran nuke deal and especially immigration. He used convenient language with Tapper when he should have said he was in favor of amnesty! Flake refuses to see the policies POTUS stands for is what the voters want, not the BS liberal progressive agenda he and many calling themselves republicans are pushing. That is why he cannot get reelected in his own district, he stands against the will of the voters. Maybe if he ran on the democrat ticket he might actually pull off a win!
The fact Flake thinks John Kasich would be a great choice should tell you all you need to know if you had any doubt!
