Switch Carter and Buchanan. Doing nothing about a national crisis is worse than having a poor economy.
Also, what's your beef with Bush 41?
Bush 41 didn't accomplish a lot in his Presidency and appeared to try to model his Presidency after Reagan's, but failed to do so.
The two landmarks of his term were the Gulf War (over in six months) and the recession, which wasn't all that severe. He could've done batter, but I wouldn't rank him among the worst.
Yeah. If you rank "not accomplishing much" as being among the reasons to call one a horrible President, you'll probably have a lot of really bad Presidents.
