Wait until he attacks lincoln as a communist for freeing the slaves or something like that

This HAS to be deliberate. I don't want to live in a world with someone being so incredibly stupid and tasteless.
I also don't want to live in a world in which he can be the presidential nominee in a big party of a powerful modern nation, but that is a truth i will have to accept.
I can't fathom this being deliberate to be honest. It is way too stupid.... What would even be the point? Are you telling me you genuinely believe that trump gave this a serious thought and concluded that attacking this family in the same way he attacks everything else was the course of action that would get him the sort of attention he wants? That cannot plausibly be a thing. The most he could have thought it "Welp, there is no such thing as bad press" but event then this is too much. He has half the party being apologetical of him at this point... Unfortunately we do live in a world where someone this objectively stupid gets to be a presidential nominee. It wouldn't even be the first time. Just look at this quotes about or from good old reagan:
"Poor dear, there's nothing between his ears."
--British Prime Minister Margaret Thatcher
"an amiable dunce"
--Clark Clifford (former Defense Secretary)
"President Reagan doesn't always check the facts before he makes statements, and the press accepts this as kind of amusing."
--former president Jimmy Carter, March 6, 1984
"His errors glide past unchallenged. At one point...he alleged that almost half the population gets a free meal from the government each day. No one told him he was crazy. The general message of the American press is that, yes, while it is perfectly true that the emperor has no clothes, nudity is actually very acceptable this year."
--Simon Hoggart, in The Observer (London), 1986
"Growing and decaying vegetation in this land are responsible for 93 percent of the oxides of nitrogen."
--Ronald Reagan, quoted in the Los Angeles Times, October 9, 1980. (According to Dr. Michael Oppenheimer of the Environmental Defense Fund, industrial sources are responsible for at least 65 percent and possibly as much as 90 percent of the oxides of nitrogen in the U.S.)
"Trains are not any more energy efficient than the average automobile, with both getting about 48 passenger miles to the gallon."
--Ronald Reagan, quoted in the Chicago Tribune, May 10, 1980. (The U.S. Department of Transportation calculates that a 14-car train traveling at 80 miles per hour gets 400 passenger miles to the gallon. A 1980 auto carrying an average of 2.2 people gets 42.6 passenger miles to the gallon.)
At least for me it was hard not to find reagan's own idiocy and complete disregard for, well, facts and knowledge oddly familiar considering trump. So not only there is area possibility of trump winning this, which is terrifying, but there is also a chance that the republican party might even like it if he does the stuff he wants to do. And then will go on to basically "edit" the parts they don't like about his record as they did with reagan. Of course, this is the age of the internet and it would be much harder to pull of than before.
