If you are saying Donald Trump is the most damning indictment of Obama then you must mean that Trump is worse?
The thing is to say someone is an objectively bad President needs some values or context.
For instance you could say he failed to meet his promises and that is the criteria on which to judge him, but is that really fair when a President can only do so much and is reliant on Congress and many other factors. Compromise is sometimes necessary. In addition, as Macmillan reportedly put it 'Events dear boy, events'.
For instance was Obama a bad President because he promised he would shut Guantanamo, but that didn't happen? Or was it because of the elements and factors opposing a solution to a problem not of his making?

I did mean trump is a worse president.. he's abject.
For me Obama was a terrible president because he promised he would:-
Deal with wallstreet
Go single payer healthcare
Not sign executive orders
Give any bill 5 days before he signed it for transparency
Shut Guantanamo
End the many wars
When in reality he did the opposite of every single one of those things almost immediately (for instance signed his first executive order 3 months into his presidency).
He also evicted 7,000,000 from their homes
Used the IRS to investigate critical journalists
Forced through the oil pipeline despite the protests of the native American Indians
Spied on political opponents
Allowed gun running to Mexican cartels
Personally signed his kill lists
Dropped so much ordnance they ran out
Aggressively went after the occupy protests
The list goes on and on...
You mistake me for believing the republicans or donald trump are good, the only difference between them is that you know it's coming with the republicans the Dems get a pass because their considered to be on 'our team'.
