A fun little match of last year’s two highly ideological presidential runners-up airing at 9 p.m. ET on CNN, which has taken a shine to the “townhall featuring A-list politician” format lately. Is Bernie really going to spend this hour pretending that he supports the ObamaCare status quo rather than single-payer or socialized medicine, as his heart surely fondly desires? Cruz should have some fun with that.

Meanwhile, some potential fun for Bernie at Cruz’s expense: Um, when is the GOP, which spent the last seven years calling ObamaCare a cancer on America, finally going to sack up and repeal it? Inquiring minds want to know, and not just left-wing minds.

In one faction are lawmakers increasingly wary of the pitfalls of a quick and sweeping repeal of the Affordable Care Act. In recent days, top congressional Republicans who are most intimately involved in health care policy have urged moderation: Fearing the consequences of a rapid repeal, they have begun to speak of “repairing” the law and even preserving aspects of it that are working.

That shift in tone has irked other Republicans who are eager to take a swift vote to roll back as much of Obamacare as possible. Their fear: their conservative constituents back home won’t settle for anything else.

“For goodness sake, we should be able to put something on President Trump’s desk that’s at least as good as what we put on President Obama’s desk. Not something watered down,” Rep. Jim Jordan, R-Ohio, told CNN in an interview. “Let’s repeal it. Let’s do what the voters sent us here to do.”

“If the House has not passed a repeal bill and sent it to the Senate by mid-March,” said Dan Holler of Heritage Action to the NYT, “that would be serious cause for concern.” At least we don’t have to worry about a firebreathing conservative like Cruz eschewing the term “repeal” for the more mealy-mouthed “repair.” Do we?

Here’s Mike Lee getting his game face on.
