“There is no doubt that Obama seriously damaged America (moral affairs, health care, etc.) and seriously damaged the international stage (Syria, Iraq, etc.)”
There is no doubt that the above is a completely false statement.
Trump supporters follow Midot Goebbels. Trump himself just installed the head for the most slanderous untruthful internet site around, Breitbart.com, as his campaign manager. Expect more of the same for the rest of the campaign.
And it was just revealed today that one of his few foreign policy advisors is a vile anti-Semite who prided himself on firing Jews while he was in government.
It is a chilul HaShem that Jews support Trump.
