Biden is definitely more right than I want him to be, and he might even hide that he's more than that via the appealing to negotiating with the other side (though there are various motivations we can attribute that to, like wanting to highlight the point of the US political system or to show that the other side doesn't want to negotiate)
The unionbusting is definitely atrocious, and I don't really think he could de-escalate anything Taiwan, and the protectionism turns me the hell off, but outside of that I think he's doing good for a guy who was initially invited in as Obama's vice to appeal to the more conservative dems (*simplifying a lot)
