Remember the middle-school retort when someone would promise to join in on something: “is that a promise, or a threat?” The line comes to mind upon viewing a video that Hillary Clinton put out this past Friday, aired by Morning Joe today.

After urging Dems to stay focused on future elections, she declares “let resistance plus persistence” equal progress. Clinton concludes, “I’ll be right there with you every step of the way.” Hillary puts extra emphasis on those last words: every step of the way. Every step? This is a woman who is not going away. Hillary 2020, anyone?

It was chuckleworthy to hear Hillary echoing the Dem buzzword of the day, as she urged “resistance.” The very symbol of the establishment suddenly transformed into Leader of the Resistance. Right.

Note: Hillary’s Twitter trolling of Trump on everything from the immigration order court decision, to Michael Flynn’s resignation, to his golf game, provides additional evidence of Hillary working to keep hope alive for a possible comeback.

One imagines the tweeting style of Trump and Hillary as very different. Trump, alone in the Tower, firing off tweets for better or worse. Hillary, ordering a team of staffers to prepare a tweet that is in turn reviewed by a committee, with perhaps some quick polling before it’s sent out.

MIKA BRZEZINSKI: Hillary Clinton tweeted out Saturday: “Congrats to DNC Chair Tom Perez and deputy Keith Ellison. Excited for strong, unified party stand for best of our country into the future.”

And on Friday, she released a video urging Democrats to stay defiant.

HILLARY CLINTON: We as Democrats must move forward with courage, confidence, and optimism, and stay focused on the elections we must win this year and next. Let resistance plus persistence equal progress for our party and our country. As long as we stand together, and work together, with respect for our difference, strength in our convictions, and love for our country, our best days are still ahead. So keep fighting, and keep the faith. And I’ll be right there with you, every step of the way.
