You should read his letter rather than just reacting. He said he is not a Trump supporter. The assertion that one is either with Clinton or is a Trump supporter is reminiscent of GWB's famous line regarding his "war on terror": You're either with us, or against us.

Hillary Clinton is the better choice of the two, but the tactics used to get her to this place were disgraceful. I watched Bill's great speech last night, and some of it did not ring true, especially the claim that they were "surprised" when New York Dems asked her to run for Senate. Her ascendancy to the Presidential nomination was ordained by the Democratic elite some time ago; Bernie Sanders knew this and claimed it, yet this was dismissed as paranoia. We all know how that turned out.

The best campaign slogan for Clinton would be - "She's not Trump. Hold your nose and vote for her!"
