Henry Olsen writes in the Washington Post:
The headline news from the most recent Post poll was that President Trump remains behind or tied with all major Democratic contenders. The takeaway should have been that if this poll is correct, Trump is almost a lock to win.
There are two reasons that this is the case. The first has to do with the electoral college; the second has to do with the likely campaign dynamics over the next year and a half. …
The Post’s poll showed Trump performing nationally at levels that suggest he would get close to or more than a majority of the vote in at least four of the five key Midwestern swing states. Take his job approval rating: The poll showed him at 47 percent approval among registered voters. The 2018 exit polls showed Trump’s job approval was higher than his national average by three points in Wisconsin and eight points in Ohio. By extrapolation, the Post poll implies his job approval is at or above 50 percent in enough states for him to carry the electoral college.
The national vote doesn’t matter unless it is a blowout.
Trump’s standing gets stronger when we look at the mock ballot questions. He receives between 46 and 48 percent of the vote among registered voters against any Democrat except Joe Biden.
Mock ballots mean little at this stage. Biden does appear the Democrat most able to beat Trump, but the other 22 contenders will probably take him down.
