The worst President, of these three?

[Mr. Smith]

Carter and LBJ both did things to change the status quo, both didn't let Congress bully them into submission and thus allow more and more polarization to creep up and gridlock everything, and both believed in a noble government that can do things.

Carter just had the misfortune of being too mean to Congress, and starting to drink the deregulation juice of doom. But his foreign policy is still the best by far and starting the Department of Education was genius.

LBJ's few sins were Vietnam and Nixonian surveillance (which are admittedly real big ones,but he did enough incredible things to overlook those such as the Civil Rights Act, Voting Rights Act, and Great Society), but everything else out of him was pretty much gold. Sans JFK and FDR he's the best of the 20th.

So yeah Obama is the worst by country mile, and not just because he fails at liberalism but because:

He's nothing but an opportunist on a good day,and a push-over to a MINORITY of Congress on a bad day (or at least it was a complete minority and could've stayed that way if he had put in more backbone). He hasn't done much of any social reform, always backing out at the last second or doing too little, most disappointing in cases such as healthcare and the environment.

When he travels, it seems to be purely for fundraising with the elites rather than much of substance.

And then there's his drones and failure to repeal the PATRIOT ACT.

[Mr. Smith]

Considering post WWII, pretty much all the Presidents except Carter were getting into all sorts of wrong and sick things...I'd say downplaying Vietnam is justifiable.

Obama and his drones, and torture, and failure to repeal the PATRIOT act, and Afghanistan even with bin Laden dead are more than equivalent to 'Nam. And Obama didn't strong arm in huge social reform to compensate, he let the GOP minority bully him, which gave them ammunition for 2010.

And the worst of 'Nam was ultimately under Nixon anyway.
