Ha ha. What do you think the answer is? The piece is by University of Houston polysci prof Brandon Rottinghaus and Boise State University polysci prof Justin S. Vaughn.

Did you guess? Trump is dead last!

Obama is up 10 since their last survey of "presidential politics experts" in 2014. He's now the 8th greatest President. Why would that be? Obama laid the groundwork for the Trump election and failed to fend off the Russians who were, apparently, bent on keeping Hillary Clinton out of office, but he's made the biggest leap in the whole survey.

Amusingly, George W. Bush has the third biggest jump, up 5 and out of the ignominious bottom 10 all the way up at #30 now.

The other big leaper was Ulysses S. Grant, up 7 to #21. Why? Ron Chernow wrote a biography of Grant. You just need the right PR.

One nice thing about this study is that it also provides separate rankings by "Democratic scholars," "Independents/other," and "Republican scholars." The Republicans don't put Trump dead last, but at #40. They put Obama at #16. Rottinghaus and Vaughn say "Trump doesn't get much of a lift from Republican-only vote: Even in their eyes, he’s a bottom-five president."

But who are the "Republican" presidential politics experts? Are they not the "Establishment"-type Republicans who deplore Trump and the people who responded to him?
