They no longer exist. FDR believed in work, in prayer and in family. Today's Democrats believe in welfare, in secularism and in alternative lifestyles. FDR would not recognize his own party today.
FDR in some ways made the party of today inevitable. He got America used to Uncle Sam's insulation from the vagaries of nature. He tolerated communists in his entourage. He negotiated with Stalin over central Europe, Korea, Vietnam, and eurasia. Most of all, he taught them that the government was their best friend.
The New Deal was probably required given the Depression. But it could have had an expiration tag attached to it.
Ever see the film about the construction of Hoover Dam? Those guys worked! That's what public projects were about in those days: providing people who wanted to work - and knew how to work - with jobs.
Don't think you're right when you say old time liberals no longer exist. I'm one of them. We're just as baffled as conservatives about the new PC reality, and perhaps even more confused as to what to do about it.
FDR tried socialism in the Great Depression and found out he liked it! All through WW2 he refered to the butcherous Stalin as 'Uncle Joe'.
Before he died, he set the stage for the 'Cold War' at Yalta and Truman foolishly went on treating the Russians as allies. For his conciliatory efforts, all he got was an 'Iron Curtain'.
If he lived today... he'd fit right in with the whole, stinking bunch!
In todays times, FDR would be a Republican. The only reason he became a Democrat in the first place was to compete with Cousin Theodore (he couldn't do so within the NY Republican Party).
