He has always been right wing. People forget that he was picked as a VP for Obama because Obama seemed “too radical” to the DNC. He was at best a centrist, at worst a 1990s centrist, which is to say, a Republican. All you have to do is look at his voting record.
I'm gonna personally beat everyone's ass if we're just caving to the right on this shit. I am not handing it to Bush Jr., Bush Jr. voters, or any of the other fuckers who've come since
I mean, one of his first acts as president was to open more concentration camps. Biden is also a right-wing extremist. He's just a politer, less blatantly unhinged one. The idea that the US is a democracy is such a joke. We criticize states like Russia for having sham elections, but ours are a sham as well since we have no choice but to vote for Democrats. There's no left wing or progressive representation at all.
"Well, we're gonna lose the left vote because we love genocide, so we should start courting right wingers who are just going to vote republican anyway"
It's extra sad because no matter how transparently they sell out their ostensibly liberal principles the libs will crawl out of the woodwork to scold you for remembering what they used to say and wanting literally ANYTHING from these fucks.
It was less than election cycle ago that Trump saying these exact things and wanting these same policies were reasons to vote for Joe. Because who would allow someone who wants to shut down the border "so we can figure out what the hell is going on" to become president?
They've reverted to a feudal mindset. The democrats have no obligation to their voters. Only the voters are obliged to swear fealty to the Dem candidate regardless of who it is and what they do.
At least that means they will stop using the "wE can PuSh HiM lEfT" line they kept trotting out last tune around, it's too incredible for even them to believe. I very much prefer him running with no platform and just shrugging off questions about why anyone should do this again. It's more honest at least.
"we're gonna elect a conservative and then push him left by defending his every action tooth and nail and promising to vote for him in the future"
Incredible gullibility
When I read the title, I immediately expected there to be at least one shitlib coming in here to defend fascist rhetoric just because it was said by Biden. And I was right. 
Do we have any words that left that aren't slurs?
Yes, lots of them
Misspeaking under the duress of the state of the union address is a far cry from "rightward lurch". I'd have to see an ongoing pattern to come to such a conclusion. But you do you.
Duress?
"Psychological pressure" like public speaking for someone with a speech impediment.
He's tried to justify his fascist speak later. It's a freudian slip, not a duress thing.
way to people who resemble a certain ethnicity? Because it's dehumanizing language that works to subconsciously justify treating them as criminals even if they didn't do anything wrong?
