Yeah - I hear you. We're having two different discussions in a sense. On one hand, there's the philosophical argument about whether Donald Trump is fit for the presidency. I believe that the available evidence, ranging from the constant questionable decisions, to the self-dealing, to the nepotism, to the unwillingness to properly learn about things that impact every American's (and to be honest, much of the rest of the world's) life, to the abuse of power and seeming inability to actually run the government correctly, (and the various criminal/civil violations contained in these actions) make him unfit. It's my belief that he should be impeached and removed on that basis - it's our duty to do so. It's NOT about policy disagreements - that, as they say, are what elections are for. Its about incompetence. High crimes and misdemeanors in the parlance of the founders, or wanton breach of fiduciary duty in the language of today.
After that, who knows. You may be (in fact I think you probably are) correct about the results of a Warren nomination, though I'm not at all convinced that her ideas are any wackier than some of the stuff I hear from the right. There will be the sexists that won't vote for her because she's "shrill" and the know-nothings who won't vote for her because she's not "someone I can have a beer with" and total fools who won't vote for her because she's a "liar" even though every third word out of Trump's mouth is a lie, and so on and so on.
I'm not sure anymore, however, that the two things are relevant to one another. For a long time I was on the side of impeachment being a bad political move for Democrats with an eye toward 2020. But the more we find out, the more I'm convinced that a Republican administration with some sort of competence and compassion (even if I disagree with their philosophies) is a fair trade to make so long as the incompetent in office now is removed. (And that's a nasty position to have to take, considering Mike Pence is pretty much a horror show himself.)
I wont disagree with you there, both far left and far right ideas are typically not very sound. But Trump is pretty much a centrist and Warren is super far left. It will be an easy choice for most of the country.
Just saw another interesting poll, all demographics for pretty much every grouping (race, sex, religion, political affiliation), with the exception of progressives, at least 2/3s thinks the economy is doing very well. So Warrens continued attack on the economy is a disconnect with typical Americans, and not only that, she is asking people to chance their new found economic success by adopting many extreme socialist policies.
Even with a downturn, I still cant see the average American getting behind these policies.
If she gets the ticket, start thinking about 2024, because it will be an easy win for Trump.
