You are just wrong. Every indication is that she will win handily. To this day she remains supported by her coalition partners. They criticize her but they love power more than doing what is right. The AFD will struggle to get 15%. Merkel remains the only leader germans trust. She ought to go, and in any other sensible democracy she would already be gone, but Germany is a strange case. My theory is it is mostly based on postwar guilt and shame.
