You think Trump's actions are less forgivable than Reagan's, yet you think Reagan should have been impeached but are, at best, unsure about Trump? Can you clarify, please?
I'll try.
I don't know exactly how to compare which one is worse.
On the one hand, Trump's actions were self serving, while Reagan was acting in what he perceived to be the national interest. (I know what Dershowitz said, but that's stupid, so we'll ignore that.) On the other hand, Reagan was acting in complete defiance of a very specific Congressional mandate, which Reagan himself had signed into law. Trump, on the other hand, was carrying out long standing policy (of controlling corruption in Ukraine) but twisting it to his own interest. At the end of the day, Congressional mandates were followed, although slightly delayed.
Either one could have been impeachable, but reasonable people could disagree on whether either one ought to have resulted in impeachment.
The difference may just be that I'm less idealistic and more jaded than I was then. I hated Ronald Reagan, and I thought somehow that mattered. I hate Donald Trump, but I'm not so convinced that it matters today.
Really, if you could make me a congressman and force me to vote in either case, I don't know which way I would vote. The actual act of voting, of making a decision that matters as opposed to just yapping about what you would do, tends to influence what you're thinking.
