Reagan is both worse than and not as bad as Harding, huh? 
Wow, that's some bad editing on my end, for other reasons
On the matter specifically, I'm rather conflicted since both were nobodies, given too much power. I think the edge goes to Reagan because he was in there longer and used more directly corrupt means to even get into office, whereas Harding was, at least, a dark horse shoved there by bosses.
Well, it's fixed now.

Putting JFK among likes of Lincoln and FDR is like putting Jeff Sessions with Lister Hill.
Considering the political record of Alabama Senators, that's not an entirely unjustified list.
