Full plate for the Sunday shows this morning, with attention split between the massacre in New Zealand, Beto O’Rourke’s entry into the presidential race, and the Senate’s vote to rebuke Trump on his border emergency. Appearing for the White House is acting chief of staff Mick Mulvaney, who’ll be on “Fox News Sunday” to say the right things about the mosque shootings, goof on O’Rourke a bit, and shrug off the Senate vote. Expect Chris Wallace to press him on Trump calling white nationalists “a small group of people that have very, very serious problems.” How small is the group globally? And what happened to there being very fine people on both sides?

The other star guests are Democrats. Leading the group is Amy Klobuchar, who’ll appear on “Meet the Press” and “State of the Union” to reiterate that personally abusing one’s employees demonstrates the sort of toughness we should look for in a leader. I’m glad I lived to see the day when being boorish to one’s staff is an electoral credential even for a so-called “progressive.” Following Klobuchar on “State of the Union” is Rashdia Tlaib, who disgraced herself (again) during the Ilhan Omar uproar by spinning the criticism of Omar’s anti-semitism as a form of Islamophobia. I suspect Jake Tapper won’t let her slide on that.

If none of that grabs you, longshot Dem candidate Pete Buttigieg will follow Mulvaney on “Fox News Sunday.” He won’t be the nominee but he’s now qualified for the debates, is an effective speaker, and made an impression on lefties in his CNN townhall a few weeks ago. Buttigieg is running mainly to raise his profile with Democrats ahead of a future statewide run in Indiana, I think. He’s already succeeded at that and we’re not even though March yet. The full line-up is at the AP.
