I just don’t think being endorsed by a hate group is comparable to voting in favor of a war crime.
Like your understatement about “don’t like”, the “endorsement” was also an understatement. Sure, the Klan was a free agent. But then Trump actually goes and works with unapologetic white supremacists. Multiple times. The endorsement goes both ways. So yeah, he’s worse in my book. And he supported the war too, he just (thankfully) didn’t have a Senate seat then. And then there’s the other reasons I gave that you didn’t quote, such as her being qualified for the job, and the fact that it was already obvious with publicly available information in July '16 that Trump was the Kremlin’s man.
Would I have liked there to have been a better candidate? Definitely. Was it a hard choice? Not remotely.
