What might that announcement be?

Wisconsin Gov. Scott Walker will announce his presidential endorsement Tuesday morning during a Milwaukee radio show appearance, his political office said Monday.

Mr. Walker signaled last week that he will endorse Texas Sen. Ted Cruz, though he has yet to make that news official. WTMJ radio host Charlie Sykes, on whose show Mr. Walker will appear, said he has not been told whom Mr. Walker will endorse.

Note that Walker hasn’t said it is Cruz, but it is Cruz.

And naturally the goof with really bad hair weighed in:

After the way I beat Gov. Scott Walker (and Jeb, Rand, Marco and all others) in the Presidential Primaries, no way he would ever endorse me!

Right. He’d never consider anything like presidential bearing, competence, relevant experience, good table manners, etc. in making his endorsement.
