In my view, it is the lack of compromise that has led us to where we are today. Clinton and Obama had their flaws, but both were objectively miles away better than Trump and George W Bush. Theres a much greater enemy to defeat in the here and now. Taking on centrists can come later on down the line, perhaps once republicans have regained their sanity and risking the election of one doesnt mean systematic oppression of anyone who isnt a cis white male.
