The Note: Trump show outshines ideology

— -- The TAKE with Rick Klein

The reality show that is the Trump White House was the main attraction again this week – from a president’s feud with his attorney general to the exit of a communications director and drama over a son-in-law, all the way through Ben Carson’s expensive taste in furniture.

But when it came to policymaking – or at least policy pronouncements – Trump was writing his own script in ways that remind conservatives that he’s played plenty of different roles over the years.

Trump’s movement on gun legislation earned an arm pump from Sen. Dianne Feinstein. And the president’s announcement a day later, on steel tariffs, might have earned him a fist bump from Sen. Bernie Sanders, had he been in the room.

Is it all strategic? Will the president truly violate conservative dogma on guns and trade and anything else that comes across his desk? Will he risk a trade war, and a war with the NRA? (And what of his favorite numbers to cite – the Dow?)

The truth is that nobody knows. More than a year into his presidency, Trump still fosters chaos for its own sake – and remains a policy enigma.

The RUNDOWN with MaryAlice Parks

Again this week, political parties seem, at best, arbitrary, and at worst, totally broken. A Republican president has Republican lawmakers dumbfounded on his trade and gun policy prescriptions and Democratic civil warring feels as hot as ever.

While Trump’s trade talk should not have surprised folks - he ran on imposing tariffs - it still felt like Republicans’ worst nightmare about this would-be populist president.

Meanwhile, Democrats in Washington will be reviewing their Unity Reform Commission’s recommendations today, and the timing feels a little ironic.

The commission was designed to build bridges between the Hillary Clinton and Bernie Sanders factions - and develop best practices for a party that seemed to have bad habits.

But on the ground, days before the first official primary voting of 2018, Democratic candidates are not just battling for votes, major Democratic institutions are aggressively battling each other.

A week ago, the organization tasked with electing Democrats to the House said it was vetoing one Democratic candidate (or at least trying to). Within a few days, the candidate, Laura Moser, who is running in the 7th Congressional District of Texas, raised more than $86,700, and gained the endorsement of Bernie Sanders’ legacy institution, Our Revolution.

The Sanders folks, still feeling like outsiders, backed the progressive Moser. The whole scene playing out in Houston put Democrats’ varied, opposing views on the way forward - smack dab into the limelight.

The TIP with Adam Kelsey

Former Vice President Joe Biden will make a long-expected trip to Pennsylvania’s 18th Congressional District next Tuesday to campaign for special-election candidate Conor Lamb, further focusing the nationwide spotlight on a race already viewed as a harbinger of Democratic chances in November.

Biden, whose hardscrabble, Scranton upbringing provides the blue-collar bona fides that appeal to rural voters in a way unmatched by other prominent Democrats, is one of the few party mercenaries Lamb has tapped to stump in the district, joining only Rep. Joe Kennedy III, D-Mass., and former presidential candidate Martin O'Malley.

Lamb’s substantial fundraising numbers — $3.2 million over the first two months of 2018 — and a recent Monmouth University poll showing a three-point race, have raised the stakes for the final week-and-a-half of the campaign. But attention is also being paid to what lies ahead for the 33-year-old former federal prosecutor, as the specter of Pennsylvania's redistricting effort looms over the race.

Not only will Lamb live in a new district come November, but both events headlined by Biden next week will take place in towns similarly located within the current 18th Congressional District - that under redistricting will transition to what will be called the 17th Congressional District. And much of that district is currently represented by Republican Rep. Keith Rothfus.

Lamb has committed to running again, no matter the outcome of the special election, but he hasn't indicated from where he’d do so, and there's widespread speculation that he'll choose to challenge Rothfus, as the demographics of the new 17th district will be more favorable to Democrats.

Upping the ante for a possible switch: On Sunday, a Pittsburgh-area LGBT group, without definitively knowing from where Lamb will be running in November, still chose to endorse him in the 17th.
