The New York Times notes Donald Trump made his pitch for a “big tent” Republican party at a rally:

“I need a Republican Senate and a House to accomplish all of the change we have to make,” Mr. Trump said. He added, “I understand and embrace the wisdom of Ronald Reagan’s big tent within the party.”

“Big, big tent,” he said. “Remember?”

He paused to ask the Democrats in the crowd to raise their hands. Hardly anyone made a sound. Mr. Trump, looking unimpressed, offered that he did not need Democrats anyway.

New York Magazine: “Both Donald Trump and Hillary Clinton have options on their websites allowing supporters to set up recurring credit-card donations to their campaigns. But unlike Clinton’s, Trump’s website has no option to cancel those donations.”

The Upshot: “Three national surveys — from Fox, NBC/WSJ and Marist/McClatchy — showed Mrs. Clinton ahead by big margins: 10, 9 and 15 percentage points. It’s the worst polling stretch for a presidential candidate at this stage since John McCain in mid-October of 2008.”

Here are the latest state polls on the presidential race:

Georgia: Clinton 44%, Trump 40% (Atlanta Journal-Constitution)

Michigan: Clinton 46%, Trump 36% (EPIC MRA)

This post will be updated throughout the day and occasionally bumped up to the top of the news feed.

The new McClatchy/Marist poll shows that among voters under 30, Hillary Clinton leads with 41%, followed by Gary Johnson at 23%, Jill Stein at 16% and Donald Trump at 9%.

Jonathan Bernstein: “In a normal election when both parties are united behind their nominee, voters will hear one message for months: that people like themselves, including the politicians they like, are supporting one candidate, while people they normally dislike or disagree with are backing the other one. Whether voters consider themselves partisans or not, that message pushes them in the ‘correct’ direction — to the candidate of the party they normally support.”

“Conventions are especially powerful in sending such signals because they dominate the news for a few days at least, drowning out the voices of the opposing party.   Even after the convention, that message can be strong — if the party is united, that is. The muddier things are, however, the less likely voters will be pushed in the ‘correct’ direction.”

“This is probably a big part of what has given Clinton a solid lead in the polls right now. The Democrats are united and sound united, while Republicans clearly are not.”
