What did anyone learn from the latest Democratic presidential primary debate on Tuesday? They learned that President Trump's 2016 victory wasn't a fluke. He really is that good at campaigning, and the Democrats are not.

Republicans know the feeling. Mitt Romney, the Republican nominee in 2012, wasn't good at campaigning, and he was up against President Barack Obama, who was.

Democrats might accept that they are now in the same situation.

Liberals in the national media like to say that Trump was purely negative in the 2016 campaign, but the opposite is true. His message to "Make America Great Again" was a vision forward, and it appealed to the people who were needed to win. And despite being called racist day in and day out by the media, Trump picked up more black and Latino votes than Romney did.

Trump did that because he, to the frustration of liberals, is an excellent campaigner. Who on the Democratic side can say the same? Joe Biden is struggling to put a sentence together. Elizabeth Warren and Bernie Sanders are knifing each other in the back. And the debate hosted Tuesday by the party that obsesses over "diversity" didn't feature any ethnic minorities, frustrating the social justice mob that now calls the shots.

What we saw at the debate is candidates who don't know what to do about the Middle East, who have no realistic answers about the rising cost of healthcare, and who thought from the beginning that Trump's "character" would be enough to unseat him.

They were wrong, and that's not something we couldn't have foreseen. Trump is a good campaigner and has had a decent first term, all things considered. That's a hard truth for Democrats to accept after the latest debate.
