Doesn't surprise me. Like I said far back in this thread, last year I received mail sent to my address, but addressed to somebody else - inside the packet was a form letter for the recipient to sign and mail back to Trump, thanking him for all he's done for America as President and living up to all of his promises of undoing everything Obama did, defeating ISIS, and making America great again in just the few months (at the time) he had been President - as well as encouraging him not to feel discouraged by all the lies being spread about him by the Democrats who were trying to make him look bad.
Also enclosed in the packet was literally like 5-6 pages of propaganda about how the "anti-American" and "anti-Christian" left are trying to destroy America from within by trying to embrace Islam, trying to open our borders, trying to drive Christianity and patriotism out of America, trying to spread false lies about Trump being a criminal and lawbreaker, blah-blah-blah, and how the recipient is encouraged to donate to a foundation dedicated to making sure that conversative, Christian, and patriotic values remain in America, and that the "anti-American" and "anti-Christian" left is defeated at all costs.
So, yeah, not at all surprising that Trump is looking for support however he can.
As for anti-Trump commercials, I have seen before the election an anti-Trump PSA done by various different celebrities - including Mike Farrell, Loretta Swit, Martin Sheen, and others - imploring the Republican members of the Electoral College to take into consideration the EC was established to ensure that only those with experience and qualifications can be nominated as a candidate for Presidency, which Trump clearly was not.
