Donald Trump’s political and media allies have worked themselves into a lather over a World Series crowd’s reaction to his appearance during a Major League Baseball game.

The president’s arrival Sunday at the Washington Nationals ballpark was greeted with a thunderous chorus of boos and then a chant of “Lock him up!”

How dare those lefty-leaning fans from D.C. disrespect the president in such a manner? That has been the response in some quarters.

My answer? Trump got just a taste of what he has dished out, or allowed his crowds to dish out, regarding a former secretary of state. You have heard those crowds shout “Lock her up!” while referring to Hillary Clinton and those email messages that vanished while served in the State Department.

She hasn’t been convicted of anything, but the crowds delivered the chants anyway. Many of them did so in Donald Trump’s presence. Did he stop them? Oh, no! He encouraged and enabled them.

Had I been in the crowd, I likely would not have joined in the chant. That’s just me. I do not begrudge those who couldn’t resist the temptation to yell the chant along with those on either side of them.

Donald Trump is a grownup. At least he is according to the calendar. Therefore, he should suck it up and take the heat.
