No, they'll get absolutely worse for her
The general public, the non-switched on politically, lets say about 50% of the population really won't know that much about her YET
When she becomes PM, they won't be able to avoid knowing who she is and they'll absolutely hate her, she won't resonate with the public and her gaffes of which there will be plenty (you only have to look back a few hours for the latest one) will rapidly turn her into a figure of fun. They'll hate her and laugh AT her
