Detroit Free Press: “With a winning message, strong fundraising and a powerful ground game, Speaker of the House Nancy Pelosi said she plans to scare off credible challengers, secure a victorious 2020 election cycle and maintain the Democratic majority in the U.S. House of Representatives by November, a year before voters cast their ballots.”

“By November, sitting and potential members of Congress will make the decision on whether they’ll run for Congress in the 2020 cycle, Pelosi told the Detroit Free Press editorial board Monday. And Democratic candidates will have the edge.”

Washington Post: “Key House campaigns reported massive fundraising hauls for this early stage of the campaign cycle, according to federal disclosures filed this past week by congressional campaigns, with all Democratic freshmen but one outraising their declared Republican challengers and several GOP incumbents lapped by Democratic opponents.”

“All told, Democratic House candidates raised $17.6 million more than Republicans between April and June.”

A new NPR/PBS Newshour/Marist poll finds that by a 53%-to-39% margin, Americans said they would definitely vote against President Trump, statistically unchanged from a month ago.

However, 54% of American voters did not vote for Trump in 2016.

McClatchy: “As they rise to the top of 2020 Democratic presidential field, Harris and Warren are increasingly in direct competition for many of the same voters and donors, according to polls and fundraising data, with each drawing support from the party’s more affluent, college-educated wing — particularly women.”

“The overlap between their supporters might be a surprise, especially for Warren, who is usually portrayed as being in direct competition with fellow liberal stalwart Bernie Sanders. But Warren’s strongest support so far has come from the same group of voters that is critical to Harris’ path to the nomination.”

Politico: “Elizabeth Warren has cut sharply into Bernie Sanders’ front-runner standing among members of the progressive political action committee Democracy for America, according to the group’s latest straw poll, while Kamala Harris vaulted ahead of Joe Biden into third place.”

“Sanders led Warren by more than 30 percentage points in the group’s previous survey in April, but the independent senator from Vermont saw his edge over Warren fall to just more than 6 percentage points in the latest survey.”

The Washington Post notes Joe Biden has been endorsed by 15 members of Congress, Kamala Harris by 12, Cory Booker by 12, Amy Klobuchar by 4, Elizabeth Warren by 4 and Bernie Sanders by 3.

By this point four years ago the majority of Democrats in Congress had endorsed Hillary Clinton.

Rick Klein: “A full week was consumed by President Trump’s decision to single out four freshman Democratic House members in singularly offensive fashion. The president continues to fuel that storyline, while this week figures to be consumed by Wednesday’s long-awaited Capitol Hill testimony featuring Robert Mueller.”

“The urgency is real for the roughly two-thirds of the field still clamoring for a spot in the fall debates. Efforts to contrast plans with Sen. Bernie Sanders’ Medicare for All proposal or Sen. Elizabeth Warren’s college-debt forgiveness plan — to cite just two prominent examples — need to be heard to get traction.”

“The condemnation of Trump has been swift and unanimous among Democrats. It’s also low-hanging political fruit — made no less tempting by the knowledge that the president would like them to pick it… Labeling Trump, though, is the easy part of the Democratic primary. It’s harder for candidates to turn the focus to something, or someone, else.”

A new CBS News poll across the early primary and caucus states finds Joe Biden leading the Democratic field with 25%, followed by Elizabeth Warren at 20%, Kamala Harris at 16% and Bernie Sanders at 15%.

“If we consider a 15% threshold as the minimum support needed to win convention delegates, then across the early states, four candidates would meet that benchmark: Biden, Warren, Harris and Sanders.”

However, the contest “is tighter now among estimated delegates across early states, the true measure of the contest — delegates to the convention. By this measure, Warren is much closer to Biden due to stronger showings especially in very liberal areas.”

Sen. Ted Cruz (R-TX) told PBS’s Firing Line that he thinks President Trump could “absolutely” be defeated in the 2020 election and predicted there could be “staggering” Democratic voter turnout.

Said Cruz: “I personally handicap the 2020 election as a coin flip. I think it’s about 50-50.”

He added: “I think we are going to see staggering Democratic turnout in 2020. Anger is a powerful motivator. The far left is pissed. They are enraged by Donald Trump, and it means they’re going to show up, and the big open question is, does everybody else show up?”
