Abraham Lincoln is considered the best by historians and Donald Trump will go down in history as being the absolute worst nincompoop of a president.
Everyone says Lincoln.
But I personally liked Harry Truman.
There’s no good way to answer this one Ray, as we can’t gauge what a given candidate would have done had they been elected.
I find it unlikely the best leaders would want to be president anyway, as they already have/had better jobs.
I find almost all politicians a bit sketchy, so there isn't a lot to choose from. I think John McCain would have made a good president. If only he hadn't picked Sarah Palin as a running mate.
Best is yet to come, all this while they merely filled the gap doling out bull crap.
