I don't know about the rest of you, but I haven't bought into the idea that Americans are stupid.
Mostly with you but then I remember the 2016 election and the 1980&1984 elections…
The two are nothing alike.
Reagan was the governor of California for 8 years, but declined to run for a third term, which he likely would've won. He had been involved in politics for decades before that, and made an experimental run at the White House in 1976. He had the experience, qualifications, charisma, and credibility to become POTUS. Don't get me wrong, I'm not saying Reagan was a good POTUS (he wasn't), but he was infinitely more qualified (and more appropriate) than the shrieking unlubricated rape machine AKA Donald J. Trump.
Regardless of how it manifested itself, Reagan really did care about improving America. Trump's only running again to save his own ass from prison and there's nothing he won't do or say to make that happen, regardless of the consequences.
