Ted Cruz is now aboard Air Force One.

Right there — that sentence — tells me a lot.

Air Force One is the plane that carries the president of the United States. It could be a two-seat prop plane; when it carries the Big Man, it becomes Air Force One.

Sen. Cruz, the junior Texas Republican, has been a harsh critic of the current president, Barack Obama.

The two of them, though, are flying to Dallas to attend an interfaith memorial service later today in honor of the five policemen shot to death this past week in the hideous rampage at the end of a peaceful march protesting two police-involved shootings earlier in the week.

The president will speak at the memorial, as will former President George W. Bush. That, too, symbolizes a remarkable coming together during this troubling time.

I wonder if the president and the senator are going to schmooze, talk nice to each other. Or will they — to use the diplomatic parlance — have one of those “frank” discussions about the issues that divide them.

Whatever. My hunch is that we well might hear a bit less of the harshness from Sen. Cruz whenever he speaks in the near future of the commander in chief.
