It's the only choice because he was shoved down Dem throats though. Great, he accomplished some things. Quite frankly any empty suit could have done that with the clout of the rest of the party. A non-geriatric progressive could have potentially done much more, but the establishment won't run anyone like that. Eventually the fragmentation will grow too great and start working against itself (we may already be there).
When Biden supported the rail corporations and waffled on student loans (pre-SC scumbaggery), it was apparent that he's just a shill. The latter went against a campaign promise, but memories are short.
Edit: also "helping defeat Russia" is arguably not a thing. They are not the threat to the US that they used to be. Sure, it's great to support Ukraine. But China is the only real military threat to the US, and Biden has been status quo there. I get that the US is world police, but let's not treat the Military Industrial Complex as a plus.
