He had no issues welcoming Nikki Haley voters to become part of his base probably because he knows how hard this election will be to win without the help of progressives and leftists. But he chose to move right instead of left, so he shouldn't be surprised when people start treating him like a 2000s era republican.
How has he moved right? Welcoming Haley voters is a sound strategy that is not mutually-exclusive to moving left, which he absolutely has on the topic of Israel.
Welcoming Haley voters is moving right. Defunding the UNRWA is moving right. The spending bill he was happy to sign still sends billions to Israel. Also, in that bill, it would limit aid to the Palestinian Authority if “the Palestinians initiate an International Criminal Court (ICC) judicially authorized investigation, or actively supports such an investigation, that subjects Israeli nationals to an investigation for alleged crimes against Palestinians.” Biden being more than willing to sign a "snitches get stitches" bill, bullying the rest of the world into letting Israel do whatever they want surely isn't moving left.
I suppose you've heard that old adage of "if a person sits at a table with 9 nazis, there are 10 nazis at the table". When trump welcomed the proud boys to his campaign, I had no doubt in my mind he was willing to cooperate with them to enact policy that would strengthen his coalition, and I feel the same about Biden with Haley Voters. It doesn't help your case that he's already pretty conservative to begin with.
I suppose you've heard that old adage of, "the enemy of my enemy is my friend." After all, we sort of utilized that during WWII to fight the nazis,
So he hasn't moved his policies whatsoever for Haley voters; he's only appealing to never-Trump voters in order to ensure the real fascist doesn't get elected. You following?
Sleep with dogs, wake up with fleas. We could likely go on with these in perpetuity. Also, a lot of Nazis were friends of the US considering Operation Paperclip happened.
Also, why would Biden need to move his policies if he's pretty conservative to begin with? More oil drilling than when trump was president. Horrible border policy. Strike busting. No protections against all the bigoted state level laws. No Supreme Court packing. No nominations for an attorney general who would actually prevent trump from rising to power again (likely because trump is probably the only person Biden even has a chance of beating in an election). Green energy initiatives that are so poorly thought out that it now costs more to install solar than before. Wanting to sign a bill to remove a competing social media platform under the supervision of Musk and Zuckerberg. Bypassing congress to send arms to Israel to support a genocide purely to acquire land to compete with china's new trade route.
Biden is willing to become a hawkish republican to win on the democrat ticket and to be seen as "strong" to would-be republican voters because he knows he's lost the left. If you're okay with the US continually walking right with every democrat and running right with every republican, just keep doing what you're doing.
And yet, you act as though the better alternative was not sleeping with the dogs and letting the Nazis win?
Which outcome would you have preferred? Think ahead here, my friend.
Also, why would Biden need to move his policies if he’s pretty conservative to begin with?
I'm simply responding to the notion that Biden is "moving right" by appealing to Haley voters. I've still yet to see any evidence whatsoever of this claim. Inviting Haley voters into a preestablished structure isn't "moving right." Saying Biden is conservative to begin with != "moving right." One is a present state; the other is a transitioning state that has yet to be evidenced in any capacity.
When we allied with the Soviet Union and china, we weren't welcoming them into our country and into our political influence. We were working with them for a common cause of defeating the nazis. Biden is welcoming Haley Voters into his campaign and they will remain there even after (if) Biden wins the election. The room is full of conservatives, so it should make plenty of sense why leftists and progressives would rather leave the room than stick around people who want them dead.
If Biden moved any more right, he'd be trump. The only thing Biden has left that's vaguely progressive is not wanting to kill people who are queer. If pinkwashed fascism is enough for you, that's fine, but you have to understand that other people have higher standards.
I seriously doubt Haley voters will be permanently welcomed in, or rather, I doubt they'll stay themselves. I think they'll dip the second another Romney-esque corporate Republican comes about -- and Biden is just too left of Romney for them to stay for long.
Either way, they're a useful tool to ensure Trump doesn't get elected. Like you said, we are working with Haley voters for "a common cause of defeating the nazis" in November. Let's not put the cart before the horse. Let's cross that bridge when we come to it. Let's worry about make-up of the party after we defeat the literal nazis in November, yes?
I don't see evidence to support the claim that Biden moving "any" more right and he'd be Trump. He'd have to transition quite a few ticks before achieving that; nevertheless, we should always embrace "less Trump" than Trump himself, so I'll take it. The thing is, I still haven't seen any evidence presented whatsoever that Biden as "moved right" to appeal to Haley voters. Until you can provide a modicum of evidence to this, I think your claim is dead in the water.
I'm sure nazis/stormfront/proud boys are also a useful tool for trump to get re-elected and he definitely didn't start changing his policy to appease them... We aren't going to agree on this, obviously. You can't change your base without changing your policy eventually. And if Biden were to suddenly grow a spine and decide to be more progressive, the Nikki Haley voters will suddenly flip to being trump voters (or any reactionary equivalent to him) because they feel lied to. At best, Nikki Haley voters means Biden will be stuck politically, not able to move left even an inch. And at worst, he is free to move as far right as he wants due to liberals being generally okay with voting for him regardless of his support of genocide.
