Final results:
The exit polls were predicting 11.5% to 11.8% vote for AfD, but they did much better. According to the final count, they got 14.2% of the vote. Merkel's party (CDU) suffered a sharp drop in support, and performed even worse than expected. Still, the CDU narrowly kept the 2nd position, after finishing marginally ahead of the Greens and the (ex-communist) Left Party.
