“If it only took one email for Donald Trump to raise more than $3.3 million, just think of the possibilities for the future of his campaign,” the Daily Beast reports.

“Of course, the operative word here is “if”—as in, if Team Trump’s boast about raising so much, so quickly were true. It’s probably not.”

“Donald Trump’s fundraising operation has been riddled with rookie errors—it’s been unsophisticated, untested and very small throughout his presidential bid, leading digital marketing experts to question whether it would be possible to actually raise the extraordinary figures he claims to have raised in a single fundraising email he sent last week.”

First Read looks at the two national polls out over the weekend:

“The biggest difference between the NBC/WSJ and WaPo/ABC polls? Our poll has Democrats with a four-point party ID advantage, while the WaPo/ABC poll has Democrats with a 12-point party ID edge. So when in doubt, average them out — and in the latest RealClearPolitics average, Clinton leads Trump by nearly seven points in a head-to-head matchup. And remember, seven points was the final margin of the 2008 Obama-McCain contest.”

NBC News/Wall Street Journal poll: “The most disliked of all is Republican presidential nominee Donald Trump, who is viewed unfavorably by a full 60 percent of the electorate, while only 29 percent offer a positive rating of the GOP standard-bearer (-31 rating). Hillary Clinton is not far behind, with 33 percent of voters giving her a favorable rating compared to 55 percent who give her a negative rating (-22).”

“For the Republican Party, it’s 28 percent positive/ 48 percent negative (-20). The Democratic Party is slightly less unpopular at 37 percent positive and 43 percent negative (-6).”

“Democrats are scrambling to make the most of the unexpected yet slender opportunity Donald Trump has given them to challenge for the House majority,” Politico reports.

“Party operatives increasingly believe that Trump’s unpopularity could create a wave that would endanger Republicans’ 30-seat edge in the House. Now, Democrats are diving into the forbidding district-by-district math, scrutinizing under-the-radar and cash-starved House candidates who haven’t gotten attention from Washington thus far, to try and get their campaigns in good enough fighting shape to take advantage of a potential Trump backlash.”

Politico: “With the convention less than a month away, Politico contacted more than 50 prominent governors, senators, and House members to gauge their interest in speaking. Only a few said they were open to it — and everyone else said they either weren’t planning on it, didn’t want to, weren’t going to Cleveland at all, or simply didn’t respond.”

“The widespread lack of interest, Republicans say, boils down to one thing: the growing consensus that it’s best to steer clear of Trump.”

The CBS News battleground tracker finds Hillary Clinton leading Donald Trump in four key states:

• Florida: Clinton 44%, Trump 41%
