As far as I can tell it's only the British GP that's banned Russian drivers for now, so he'd only miss one race as the FIA are allowing Russian drivers to compete under their neutral flag.
Make no mistake though, absolutely no fan of his. All the pearl clutching about his boob touching seemed to distract people from his terrible conduct in F2, which should have precluded him from motorsport competition just about anywhere. The real issue is the alignment of daddy Dimitry and a certain agitator ATM. I don't think even pre-2022 people would have missed the Mazepin name, but it seems a no brainer now. If they do exit and Haas can continue, seems like Pietro would be the logical choice. Would be awesome to see Oscar Piastri on grid though. The Hulk, while possibly the hardest done-by driver who truly deserves a drive, likely wouldn't join as he'd want to get paid, and fair enough.
The ultimate issue at hand is the damage to the Haas brand. Between on-track performance, the Rich Energy debacle and now, it hasn't been a great run. I don't really know what heritage, if any, Gene has in motorsport, but it seems at this point the best bet would be for him to get bought out. With Andretti keen as to join, it'd be great to see, although I would love more cars on track. If he does take over Haas, there should be only one stipulation - Guenther must stay!
