Which "left"?? You mean politicians? The wealthy? The hate for him crosses party lines with few exceptions.
Regular people though? That's a different story. Not sure it is mostly people leaning left though. It wouldn't be the first time GOP supporters licked the boots as they press against their necks, so it wouldn't surprise me.
Isn't the party motto like "Pls tread on me sirs!" or something?
They compromised and it's central.
