Trump makes the rounds in Washington to unite the Republican Party before the Cleveland convention, and he leaves threatening Arizona Sen. Jeff Flake with working to defeat his 2018 re-election bid if he does not jump on the Trump bandwagon and support his nomination. Flake publicly criticizes and disapproves of much of Trump's quackery, and he does not endorse Trump because he has conviction and integrity. Flake, apparently, is not a spineless, puppet-like hypocrite who can be manipulated.
