People who believe that you have to be a bully to be "strong" think that he actively hurt the country by being President.
He was the first President to not be re-elected in almost a century, the voters would rather have Reagan, and not only was it a pretty clear popular vote win; I had no idea until I looked it up just now, but Reagan had a mind-boggling 10:1 electoral vote ratio.
Those are the older people, have they re-assessed him as the years went on?
Of course, not everybody votes. A bit over half of the eligible voters did.
