I'm not a fan, although I did vote for her in 2016 because the alternative was a shitstorm. Why don't I like her? It's probably a stupid, petty reason but it exemplifies how I see her. A day or so after 9/11, W was addressing the assembled chambers of congress. I loathed him as well, but he was doing his best to bring us all together in a united front against those who attacked us. As he was speaking, the camera was slowly panning across the solemn faces of the Senators and Representatives present. It caught Clinton smirking and whispering to whoever was sitting next to her, like a bratty teenager. To me it was appalling.
I don't believe all the bullshit lies the Reichwingers have made up about the Clintons for decades. Mrs. Clinton, as far as I can tell, served honorably both as Senator and Secretary of State, and was well-respected by others. But that one moment did it for me. It illustrated her character in a spotlight.
