The 2020 presidential election campaign is taking shape. Democrats are lining up seemingly by the dozens to campaign against Donald J. Trump, the Republican incumbent.

I’ll have more to say about the contenders later. Today, I feel the need to explore the type of campaign this incumbent president is going to wage.

Donald Trump had no public service record to commend him for election as president in 2016. He relied instead on a phony argument that he was a self-made zillionaire who worked hard to build a real estate empire from scratch. It turned out that isn’t the case. Voters bought it anyway and he was elected.

Now he’s running for re-election. As the incumbent, the president has a record now on which he must run. He is going to be asked to defend his record. How in the world is he going to do that?

The nation already has undergone two partial government shutdowns on Trump’s watch; a third shutdown might occur at the end of the week. He has groveled in front of Russian strongman Vladimir Putin, refusing to acknowledge publicly that Russians attacked our electoral system in 2016. Trump has heaped praise on North Korean despot Kim Jong Un after threatening to blow his country to smithereens with “fire and fury” the likes of which the world has never seen.

He went to Europe and scolded NATO allies because they weren’t paying more for their defense; along the way he has hinted that the United States might withdraw from its most vital military alliance.

Trump campaigned in 2016 on a pledge to build The Wall along our southern border and said “Mexico is going to pay for it”; Mexico isn’t paying for it, period, meaning that he wants you and me to pay the bill. The president’s rhetorical clumsiness has revealed a host of frightening views, such as his assertion that the KKK/Nazi rally in Charlottesville rally and riot included “fine people, on both sides.”

Now that Trump has a record to defend, I am left to ask: How in the world is this guy going to sell it to voters? How does he reach beyond his base of supporters to ensure that he gets re-elected?

He has spent his term in office kowtowing to his base. He has done damn little to reach beyond that core 38 percent of voters who think he is the best thing to happen since pockets on shirts.

Just as Donald Trump defied conventional wisdom by being elected in 2016 with zero public service experience, he seeks to do it again in 2020 by defending a presidential term that has far less to show for it than he will trumpet along the campaign trail.

He savaged his Republican primary foes with insults and innuendo en route to the GOP nomination in 2016; he continued to toss grenades at Democratic nominee Hillary Clinton. I look for much more of the same from the incumbent this time around.

The 2016 presidential campaign was ugly enough. The 2020 campaign is looking like a bloodbath.
