Reagan wasn't a perfect conservative or a perfect president. IMO, that's just part of life.
It took 60 years, by my reckoning, to get us where we are now. Those who insist we can get it all back in one swing don't understand where we are or how we got here...remembering that the biggest problem wasn't that there was an Obama but that he could be elected to two terms.
Again, “better” is a matter of opinion. A full 40% of the country believe that America is better off than it was 7 years ago.
But I understand what you are saying. My issue with Donald Trump is that I don’t know if my understanding of “better” and his understanding of “better” align.
