Disagreed about "play President", but I do agree that Reagan knew how to use the system and not get used by it.All Trump had to do is "play president"
Go to meetings, shake a lot of hands, smile for the cameras
Reagan was quite good at it
Do that and Republicans pass legislation, Trump signs it, the economy is strong.....Trump gets reelected
But Trump can't help himself. He can't ignore the small stuff. He had to accuse Obama of a crime
Then there is that Russian thing.......
As for Trump, I do agree he gets wrapped up in minutia. His Twitter account is the biggest detriment to his Presidency and, IMO, the main reason for his disapproval ratings:
RealClearPolitics - Election Other - President Trump Job Approval
His 140-character rants make him look like a conspiracy kook whereas Reagan was eloquent and well-spoken.
