I’ve been arguing this for a year. If not for Obama plus the failed GOP opposition then no Trump. I joined the campaign in late Dec/early Jan with that understanding.
It is not just Obama. It is the entire political left tolerating an authoritarian wing that says not only “we’re good, smart, rational, tolerant, moral - and you’re stupid, evil, crazy” BUT “we’re so good, and you’re so evil, we don’t just have to ignore you or mock you but physically attack you for daring to do anything but cower and hide”.
I agree with that, and would add: for me, Trump’s ascendancy has Boehner and McConnell written all over it.
