The Note: GOP candidates rallying behind Trump Does Trump see the midterms to be a referendum on himself and his agenda?

The TAKE with Rick Klein

He may quarrel with himself on the importance of the midterms. But if President Donald Trump wants them to be a referendum on himself and his agenda, he’s getting his wish.

Trump's visit Tuesday to Nashville highlights the unmistakable trend: There is virtually no room between Trump and the Senate candidates hoping to maintain his Republican majority this year. And Republicans appear far more comfortable touting Trump’s leadership than Democrats do arguing against it.

Trump claimed that his sway drove Sen. Bob Corker from running for another term in Tennessee, and kept him out when he flirted with returning after all.

In his place is Rep. Marsha Blackburn, who faces only nominal opposition in August’s GOP primary. She is set to join nominees who have already emerged out of states including Indiana, Ohio, Pennsylvania, and West Virginia, by winning fights that centered on who the most staunch Trump loyalist would be.

It’s also telling that while Trump is primed to attack the likely Democratic candidate in Tennessee, Phil Bredesen, Bredesen is already on TV promising to "separate the message from the messenger."

"Look, I’m not running against Donald Trump," Bredesen said in a recent campaign ad.

The RUNDOWN with MaryAlice Parks

No, there is no law requiring immigration officials to separate children from their parents. But yes, federal agents are now forcibly removing minors from parents suspected of illegally crossing the border (regardless of the minor’s age), according to members of the Trump administration and experts in the field.

The new practice was devised and implemented by the Trump administration this spring and does not have anything to do with "Democrats," despite the presidents’ false statements on Twitter.

Instead the protocol is a consequence of a larger change in policy under this administration, a decision to criminally prosecute all reported illegal border crossings. Now, even people who might be seeking asylum, for example, could potentially be subject to jail time not just deportation.

The "100 percent" prosecution policy raises serious questions: Does it make sense to have for-profit prisons and detention centers? Are federal agents receiving training to limit trauma for children? Should the federal agencies be trusted to care for an increase of minors in their custody, when they admitted losing track of 1,475 minors last year? If illegal crossings are down, but gang violence in Central America is up, does it make sense to the U.S. federal government to be looking for the toughest, and, arguably cruelest, ways to deter those seeking refuge?

The TIP with Esther Castillejo

Polls in California will be closing exactly one week from today and with just seven days to go, Democrats outside the Golden State have spent more than $8 million trying to avoid electoral calamity in congressional races.

An ABC News review of Federal Election Commission records show that, as of Friday, different Democratic groups have spent big bucks flooding the airwaves, stuffing mailboxes and spamming social media.

This spending is in races in just three seats: the 39th, 48th and 49th Congressional Districts. All are in Southern California, and all are currently held by Republicans, only one of whom -- Rep. Dana Rohrabacher -- is fighting for re-election.

The most money has gone into the 49th Congressional District, a seat left vacant after Rep. Darrell Issa, R-Calif., announced he wasn't seeking re-election.

There, two Republicans with party backing have been successful in rallying the traditionally conservative district and pulled ahead of the pack, threatening to shut Democrats out of the race and effectively stop the so-called "blue wave" Democrats sought to ride into House victory.

California is the first state using a top-two primary system for congressional races to vote this year. In a top-two system, also called a "jungle primary," the two candidates with the most votes advance to the general election regardless of party affiliation.

Not getting a candidate in at least two of these Republican-held Southern California seats would be disastrous for Democrats hoping to take back the House.
