I could do the same thing this guy does, imagining what the Founders would think of a lot of liberal platform planks. Federally-funded abortions might go over well. Or Federal control of every aspect of our existence, and a tax maw that consumes a third to a half of the income of the average American. (up until around the Civil War, almost all of Federal revenues came from tariffs.)
Hey, let's take a Founder survey on votes for black people!
As for the rest, go ahead. Run Dodd. Or run an atheist for President. Find out how "right of center" America is.
