I was looking at list, and thinking about the rating -
Many posters bring up FDR, Potsdam, etc -
Note that if you ask "What were worst US Presidential actions for leftists/communists" you get a very differnet look -
For instance - Potsdam was good for commies.
Starting/(escalating) Vietnam war? Commies end up winning and US embarrassed - thus not bad.
Reagan and Contras - bad for commies - on list
Clinton and Iran - good for anti-americans - not on list.
Nixon's non-impeachment rated higher than Clintoon's actual impeachment, and subsequent loss of respect for law in US? Just typical leftist spin.
I'm no historian - I just noted a bit of a trend. The freepers treated the question as if "bad" meant bad for the US/ I'm not sure the hoistorians did.
