>> the most pandering, corrupt administration in American history?”

Hmmm
Falsifying a basis for the Vietnam war?
Watergate?
Selling weapons to Iran?
Getting one's jollies with an intern in the White House?
Auctioning the Lincoln bedroom to highest contributor?
Selling presidential pardons to Swiss billionaires?
Telling the world that Iraq has WMD?
Hiring Halliburton?
Outing a CIA agent for political reasons?

One of the nice things about getting old is that you get to see people in the context of time.
Even lily-white Ike took some gifts that he shouldn't have.
There's a cabin named after him at Augusta National. He stayed there when he played as President. Do you really think that he paid a greens fee?
Obama is corrupt but for none of the reasons you cite. We can have a good dialogue about that sometime, I'm sure.
Of the presidents I've seen, when it comes to corruption Ike, JFK, Reagan, both Bushes, Carter and Obama are all little leaguers when compared to Johnson, Nixon and Clinton who made it an art form.
Johnson did it because he craved power and would do anything to seize it.
Nixon did it because he was nasty and wanted to make his enemies squirm.
Clinton did it because he's enormously gifted but equally flawed and has the ethics of a slug.
And .. to make things worse.. he takes lessons from Hillary.
