Because Trump has broken decisively with the Neoconservatives, the warmongering faction of the GOP, who have been behind pretty much every US war since 2000. He has also pushed the GOP to the left on economics, even if this is a rhetorical play.
But it is strange how most people on the Left can’t see this or notice its significance, as Michael Hudson explains:
Note well: over at the Weekly Standard, which is pretty much Neocon Central, there is as much hatred of Trump as on the left.
Neocon warmonger-in-chief Bill Kristol, in his latest screed there, is now opining that Trump is the sock puppet of Putin.
Bill Kristol, you might remember, was behind the Neocon push for a third party candidate to run against Trump.
Kristol made noises about a third party candidate called David A. French. Unfortunately for Bill, that all collapsed when French decided not to run. Part of the reason may have been that French has a somewhat, err, “controversial” opinion: he agrees with Kevin Williamson that the American white working class should die.
And the Neocons wanted this guy to be president of the United States?!
