* We haven’t talked about the Republican presidential primaries that took place yesterday. There were four of them: Mississippi, Michigan, Idaho and Hawaii. Perhaps the reason we didn’t focus on them is that the results were Trump, Trump, Cruz and Trump. Not much new to report there.

* The one thing that came out of yesterday’s Republican primaries is that Marco Rubio should feel his ears burning. Lots of people are talking about him…and not necessarily in a good way. Jennifer Rubin crafted a speech that someone should whisper in his ear.

Stay in and you risk losing your state, ending your career on a terrible note and getting blamed for taking just enough away in states such as Ohio and Illinois to give Donald Trump, a man you have all but said is unfit for office, the nomination.

Right now — until March 15 — you have remarkable leverage. You can endorse Sen. Ted Cruz (R-Tex.), asking that your roughly 150 delegates (more than enough to put him in the lead) vote for him, and likely get the vice presidential spot.

* On the other end of the Republican spectrum, the folks at Red State are sending the same message to Rubio.

We know Marco Rubio has that fight in him; we’ve seen it before, from his underdog challenge to Charlie Crist to his comeback from the disappointment of New Hampshire to his upbeat push to continue fighting Donald Trump in Florida right now. But when people have invested their trust and their efforts in you, character and judgment also call for knowing when to stop fighting and cut a deal. The time for Rubio to do that is now – if not today, then no later than after Thursday’s debate. You have undoubtedly read many efforts in the past week by Cruz supporters, Trump supporters, Kasich supporter(s), liberals or anti-Trump party-unity Republicans to convince Rubio to get out of the race. But let me focus mainly on why striking a deal now to be Ted Cruz’s running mate would be in Rubio’s best interests, and is therefore something Rubio’s supporters should now actively desire.

* Speaking of Rubio and Cruz, they’ve made it a habit to bellyache about President Obama’s actions to normalize this country’s relations with Cuba. It sounds like they’re not getting much support for that position from their Republican colleagues in Congress.

It wasn’t so long ago that a small congressional delegation’s trip to Cuba was a less-than-popular outing. But at least 20 lawmakers will accompany President Obama on his trip to Cuba this month, and many more asked for a seat aboard Air Force One. The group is bipartisan, demonstrating that some Republicans are coming around to the idea of ending a decades-old trade embargo, a policy Mr. Obama and President Raúl Castro of Cuba have pursued.

* Nina Totenberg reports that President Obama is in the process of meeting with potential Supreme Court nominees.

Sources close to the process say that among those being interviewed are Chief Judge Merrick Garland of the U.S. Court of Appeals for the District of Columbia; Judge Sri Srinivasan, of the same court; Judge Paul Watford, of the 9th Circuit Court of Appeals based in San Francisco; Judge Jane Kelly, of the 8th Circuit Court of Appeals based in St. Louis; and U.S. District Judge Ketanji Brown Jackson, who serves in Washington, D.C.

* I really love this piece that Kevin Drum wrote today. It is titled: Americans Aren’t Anxious About the Economy. So What Are They Anxious About? In a totally logical fashion, he walks through various possibilities of what might be creating the anxiety we’re hearing about so much in this election season and provides data to get to his final conclusion – which is a whopper.

* Finally, this ad from LBJ’s 1964 presidential race against Goldwater is making the rounds on social media right now. It is unbelievably prescient.
