The Note: Democrats could see better days according to poll, leaving Trump and Republicans on defense 60 percent of registered voters say they’d prefer Congress be held by Democrats.

The TAKE with Rick Klein

Two months out, it’s easy to see how things might get worse for President Donald Trump and the Republican Party – and less easy to see how things could get better.

A 14-point gap in the generic ballot – a 52-38 edge for Democrats over Republicans in House races – highlights the ABC News/Washington Post poll out Tuesday morning. Sixty percent of registered voters say they’d prefer that Congress be controlled by Democrats, to act as a check on the president and his 36 percent approval rating.

The numbers reflect weakness in the GOP brand, as redefined by Trump, than any particular strength for Democrats. Republicans will argue that Democrats plan to impeach the president if they take control of Congress, but 72 percent of voters already expect that to happen.

This figures to be an enormously consequential week, with Brett Kavanaugh’s Supreme Court confirmation hearings vying for attention with technology companies in Capitol Hill and more rounds in Trump’s political war against his own attorney general.

But the big consequences of Trump on the Republican Party are already in stark view.

The RUNDOWN with MaryAlice Parks

Fuming over corruption investigations against two of his congressional loyalists, President Trump tweeted this weekend, "Good job Jeff..," taking a sarcastic, venomous swipe at this own Attorney General Jeff Sessions.

The president argued in his political tweet spree that indictments against these two Republicans members of Congress could hurt their chances in the midterms.

Ironically, the president's statements could also make life hard for his Supreme Court nominee Brett Kavanaugh. Appearing in front of the Senate Judiciary Committee this week, the aspiring justice will no doubt be grilled about his own opinions regarding Sessions and judicial independence.

Kavanaugh is facing tough opposition from Democrats as is. Activist groups have been digging through his prior opinions and noting controversial decisions he made on environmental protection, health care and labor rights.

The NAACP President Derrick Johnson announced yesterday he plans to attend the Senate hearing Tuesday, writing in a statement: "What we do know of Judge Kavanaugh’s civil rights record is deeply troubling. His views on voting rights, affirmative action, equal employment, fair housing, and criminal justice could shut the courthouse door on justice for a generation."

According to the latest ABC News/ Washington Post poll, 39 percent of Americans do not think Kavanaugh should be confirmed — 38 percent do. Comparatively that places Kavanaugh as one of the most widely unpopular Supreme Court nominees in modern history.

The TIP with Benjamin Siegel

In one of the last primaries of 2018, Democrats in Massachusetts's seventh congressional district will be choosing between two true-blue progressives: Rep. Mike Capuano, a veteran antiwar lawmaker whose seniority could become more relevant in a Democrat-led House, or Ayanna Pressley, a city counselor with sharper elbows who says a progressive voting record is a "baseline," and wants to be a more activist leader in Washington.

"Seniority without leadership doesn't mean anything," she said Monday. Capuano says his knowledge of Washington makes him the best "fighter" the district can send to Congress to challenge President Trump.

Capuano, the favorite who is expected to retain his seat, has a large base of support and is popular among many segments of this majority-minority district. Still, some voters have yet to make up their minds.

"I think they both have something rich to offer," Anna Thal-Reno, 70, a retiree, who said on Monday that she was leaning toward Capuano but had not firmly decided on a candidate.

While Pressley hasn't said whether she'd back Nancy Pelosi for speaker should she win the primary, an upset in this race could send a message to Democratic leaders in Washington about who voters want their leaders to be and how they want them to lead.
