I'm not a Trump lover, but I definitely am happy he was elected over HRC. For many reasons.
There's your answer then. If you view yourself on the conservative end of the spectrum and chose Trump over Clinton, then on some level you associate Trump with conservatism (or at least more conservative than Clinton). Therefore any Trump criticism you encounter will be perceived as coming from the left. Lots of Trump criticism at the ISF ---> your perceived big shift left.
