I would re-read my post. It was clear and straightforward. I did not compare Obama and Trump. I said Obama lowered the bar first. If there was no Obama, then there would be no Trump. This thread is about the 2020 Democratic candidates. If you want to start a thread comparing Obama and Trump, go ahead and do it.
I'm not starting a new thread, I'm responding to your posts in this thread.
Again, Obama didn't lower the bar.
Again, Obama was more qualified that Trump.
Again, Obama was less weird than Trump.
All of the above are obvious and can be strongly supported by evidence.
Trump doesn't need a low bar to run for President. He's extremely narcissistic and appears to have a low IQ. If he decides to run, he'd run regardless of "the bar." (As he did unsuccessfully and briefly in the past ... before Obama. So no, Trump didn't run again because of Obama.)
Again, if you don't want serious debate, we'll just have to agree to disagree.
Consider occasionally admitting when you're wrong. It would do wonders for your credibility.
