Was Paul Ryan a good VP pick for Mitt Romney?

[Okay, maybe Mike Johnson is a competent parliamentarian.]

Ryan actively harmed the ticket by reinforcing the perception of Romney as a heartless plutocrat. People forget this today because Romney is a relative moderate on the flashpoint issues of the Trump era, but at the time he came across as a cartoonishly extreme Scrooge McDuck type, and Ryan cemented that. "Soothing Midwesterner" was the right instinct but someone with a more "common touch" image, or an image that could conceivably have been "spun" in that direction (which Ryan's couldn't have been in a month of Sundays), would have gone over better.
