for context, yes, the conservative CDU is moving right, but only after having moved left in their coalitions with left wing parties. So, now they're actually becoming conservative again to be competitive with the AfD
There are between 5 and 7 parties that theoretically could make it into parliament and Germany will always be ruled by a coalition. But there is a non-zero chance it will be one between conservatives and nazis.
There is still a "conservative" party on the spectrum, too. But they have turned further right in response to this development and they're not going to win a majority.
