It’s very difficult, because GOP presidents always just want to let by gones be by gones and move ahead - which I think is a great idea. But to my knowledge, no modern Dem has ever done that.
The press is part of the problem; can you imagine how they would be howling if any of the cutely named “scandals” (actually gross legal and constitutional violations) committed by Obama were happening under a GOP president? For one thing, any GOPer who did what Obama has done wouldn’t even be in office anymore, and he’d be lucky not to be in jail.
Bush was a remarkably clean President. The Dems were desperate to find scandals in his admin and there were none so they had to invent one (Valerie Plame).
The MSM went on for months about Plame...there was NOTHING there!
With Obama there has been a new scandal every week from Day One. The MSM covers it for a day or so and then move on...leading the public into thinking there's nothing there.
