OPINION: Dem debate reveals wacky things required of liberal candidates. This is how to defeat Trump?

The greatest problem facing the U.S., according to the Democratic presidential candidates who appeared at their first debate Wednesday night, is the power of large corporations.

Sen. Elizabeth Warren of Massachusetts and her colleagues assured us that it is big business that is to blame for gun violence, drug addiction, mass incarceration, inadequate health care, illegal immigration and the plight of working people.

The Democratic presidential hopefuls want to raise taxes on corporations, break them up and rein them in.

Warren’s most passionate moment of the evening came when she interrupted to claim that health insurance companies were “sucking” $23 billion in profit out of the health care system. She’s not the only one singing that tune.

Winning the Democratic nomination in 2020 apparently requires convincing voters you can defeat President Trump, that you are 100 percent committed to addressing climate change, and that you are more than ready to go toe-to-toe with nefarious corporate interests.

Interestingly, math does not seem to be a prerequisite.

Not one candidate was pressed by the evening’s left-leaning moderators to explain how they would pay for the generous programs they all endorse. There was not a word about the cost of the Democratic free-for-all (free college, free health care, and more) that we’ve heard so much about.

So who came out best at the end of the night?
