It's my opinion that she has been dreadfully treated by the public faces of her party. She is a well meaning woman who has had no support and has been publically embarrassed and attacked time, and time again. The treatment of her has been appalling, she is doing the best she can with the worst hand a PM has ever inherited and it is no wonder people aren't happy. Brexit didn't mean anything when she became the PM, she has defined it. The deal isn't brilliant for anyone, but neither is the thing which was voted for - there was no clear expectation of what would happen in the event of the Leave vote. The people moaning are the people who always moan, whatever the circumstances.
Rather hard to have any sympathy with her when she put herself forward for the role of PM ..... she didn't get it shoved on her. Throw in her lies and I have even less sympathy with her.
