He is exactly right.
Before AfD, there'd never been a successful right-wing extremist party since Germany's transition to democracy. Sooner or later they were all gone – either from a lack of relevance or due to their own incompetence.
The strength of AfD is the weakness of all others. Their own honorary chairman Alexander Gauland has said as much.
I can only encourage everyone in here to think for themselves and not simply cheer for AfD because you deem them the ideological equivalent of whatever right-wing party you support in your home country. Odds are they're not. There's a reason why Marine Le Pen, Giorgia Meloni and Geert Wilders don't want anything to do with them.
Even Elon Musk seems not to be immune to the "enemy of my enemy" fallacy, elsewise he'd realise an AfD-led government would be hugely detrimental to his business interests in Germany (which he claims to protect by supporting them). Their economic manifesto is anything but laissez-faire. Tesla's German factories could close if AfD had it their way.
AfD is incompetent, they're weird, and they do have some actual Neo-Nazis amongst their ranks. Several of their cadre have proven ties with Moscow and Beijing. The legitimate nature of many of their complaints doesn't change that.
Most importantly, they do not have and never will have majority appeal. Their catalogue of demands (especially their wanting to leave NATO and the EU) isn't just anathema to other political parties, but also irreconcilable with a large majority of the populace.
And frankly, I don't understand why so many on the right in Germany only ever expect CDU to make concessions towards AfD. The latter might as well take one for the team and postpone or abandon some of their more unrealistic demands to make a coalition possible. It's not just CDU needing a partner on the right side of the aisle; AfD needs a partner as well (unless they're content never to govern).
Anyways, Merz has proven over the past few days he really means what he says. He's proven he doesn't want to form a coalition with the Social Democrats nor the Greens. In fact, he blocked that road for good on Wednesday.
What our election system would necessitate right about now is for AfD supporters to realise the only way to prevent another left-leaning government is to turn out in droves and support Friedrich Merz. Unfortunately, they'll be too disenchanted or too stupid to realise that.
Politically, we're looking at a very bleak situation. Based on current predictions the upcoming elections won't produce a viable government.
