Jonathan Chait on Mr. Trump's exploitation of the tragedy in Orlando yesterday. I don't think it'll work to base his campaign on the premise that he'd be tough on terrorists, whereas Hillary Clinton would be weak. Trump's credentials in that area are nothing but a lot of tough talk, whereas Hillary Clinton has some experience. Besides, I don't think the swing voters — the ones who haven't decided yet which candidate is the lesser of two evils — perceive Hillary Clinton as weak. They have other issues with her relating to honesty and ambition. And I think Trump already has all the support he's going to get from people who want to deport all Muslims and keep any more from getting in.
