Trump is a man on an island -- and losing

Yesterday, we saw President Obama and Hillary Clinton deliver a tag-team slam on Donald Trump over the presumptive GOP nominee's reactions to the tragic Orland shooting. "Are we going to start treating all Muslim Americans differently?" a visibly angry Obama asked. "Are we going to start subjecting them to special surveillance? Are we going to start discriminating against them because of their faith?" Almost at the same time, Clinton added this: "One day after the massacre, [Trump] went on TV and suggested that President Obama is on the side of the terrorists. Now just think about that for a second. Even in a time of divided politics, this is way beyond anything that should be said by someone running for president of the United States." Trump delivered his own counterpunch at his rally in North Carolina. "I watched President Obama today and he was more angry at me than he was at the shooter." But as the Democratic Party has rallied around Clinton (save for Bernie Sanders -- more on that below), Trump is pretty much all alone here in his reaction to Orlando. "I'm not going to be commenting on the presidential candidates today," Senate Majority Leader Mitch McConnell said, per Benjy Sarlin. "I am not going to spend my time commenting about the ups and downs and the in-betweens of comments," added House Speaker Paul Ryan. And then there's this: "Senator Tim Scott, R-S.C., paused a moment after being asked by NBC News whether he had any thoughts on Trump's response to Orlando. 'You know…hmm,' he said. Then without another word, he walked onto the Senate floor." Hmm indeed.
