Just this week I followed a series of tweets from Jared Yates Sexton, the man who attended last month's Trump rally and was so graphic in his descriptions. This week's rally was Trump's Indiana rally with Governor Mike Pence.

Sexton told me on Twitter that there were many, many children at a rally where participants called for Hillary Clinton to be hanged and others shouted out that she was a c*nt. As a parent, I cannot imagine a time where I ever would have taken my kids to something like that. Ever.

And it's having an impact, as Huffington Post reported earlier this year.

“My students are terrified of Donald Trump. They think that if he’s elected, all black people will get sent back to Africa,” one middle school teacher told the SPLC. The teacher was one of more than 2,000 educators who opted to take a survey conducted through the SPLC’s “Teaching Tolerance” program.

“I have had Muslim students called terrorists,” said another teacher who submitted comments to the survey.

“There is a boy from Mexico, who is a citizen, who is terrified that the country will deport him if Trump wins,” wrote a third teacher. “He is also scared that kids and grown-ups can and will hurt him.”

Of all the ads the Clinton campaign has released, this one is the most visceral and effective. Kudos to her team for this.
