The Note: Can Democrats beat Trump’s GOP with Obamacare? Trump has said the fight over Obamacare continues. 2018 candidates welcome that.

The TAKE with Rick Klein

Obamacare once sparked a political backlash that cost Democrats control of a chamber of Congress.

Eight years later, it just might be what gives them a fighting chance at taking another chamber back.

The political potency of health care will be on fresh display in West Virginia on Tuesday. President Donald Trump is making his sixth visit to the state as president, as he seeks to oust an incumbent Democrat who wants his campaign to be about saving Obamacare.

Sen. Joe Manchin is attacking his GOP opponent, Attorney General Patrick Morrisey, for his attempt to get Obamacare’s pre-existing conditions guarantee ruled unconstitutional. Manchin says 800,000 West Virginians could lose health care if the Trump administration effort – joined by 20 state attorneys general - succeeds.

Tellingly, Manchin’s arguments are being echoed by Democrats in tough re-election fights in states including Missouri, North Dakota, and West Virginia. Trump has said the fight over Obamacare continues – and the men and women he’s trying to defeat are welcoming that.

The RUNDOWN with MaryAlice Parks

Democratic women are poised to make history again on Tuesday.

The frontrunner in Wyoming’s Democratic gubernatorial primary, Mary Throne, could be the tenth Democratic woman nominated in a governor’s race this year. That number would set a record for the two major political parties.

Throne, a former state representative and minority leader, is facing two other Democrats in the primary. She says she is running to protect public education, invest in infrastructure and stabilize the local government budget and spending.

Of course, Wyoming is a deep-red Republican stronghold. Should Throne win her primary Tuesday night, she will likely be considered the underdog almost instantly in the general election.

The GOP primary field is jam-packed with five men and another woman, a lawyer and state rights advocate, Harriet Hageman.

Nationwide, Republicans have nominated four women in governors’ races this year, compared to nine for Democrats. Both parties have more women on gubernatorial primary ballots still to come.

The TIP with Elizabeth McLaughlin

While the president's call to cancel the military parade he wanted was abrupt, the details of how he decided have been slow to surface.

Pentagon spokesperson Col. Rob Manning acknowledged Monday that nobody at the Pentagon had informed Trump of the latest estimates for the November 10 event beforehand -- or of the range of options prepared.

"The president was not briefed by any member of the Department of Defense on any cost associated with the parade," Manning told Pentagon reporters, before referring questions to the White House, which didn’t respond to an ABC News request for comment.

So, the president apparently canceled the parade he ordered either after seeing news reports about a new $92 million estimate, or after a member of his staff told him about new cost figures but didn't inform or check with the DoD.
