I guess this had to be one of the biggest non-surprises of the 2019 World Series.

Donald Trump showed up tonight at the Washington Nationals ballpark in D.C., while the Nats were playing the Houston Astros in the fifth game of the World Series. The public address announcer told the crowd of more than 40,000 fans in the third inning that the president was among them.

The crowd reaction? They booed loudly and then began chanting “Lock him up!” in a move reminiscent of the “Lock her up!” chant heard during the 2016 presidential campaign; the former chant, of course, was aimed at Hillary Rodham Clinton and her now largely debunked e-mail controversy.

But now the president is facing, shall we say, much more serious charges of corruption and violation of his oath of office. He is likely to be impeached by the House of Representatives.

So he goes the ballpark for a little “down time” from the rigors of the impeachment inquiry and killing of the Islamic State guru in Syria.

He got the greeting he deserved and quite likely expected to receive from the Nationals crowd.

Is he disheartened by it? Hardly. That would require a conscience on the part of the president.
