There's a 0.00000% chance and progressive immigration activist ever votes for Trump. That's an empty threat if there ever was one.

And yet you continually argue that Biden (and now Harris) might lose votes if they take the wrong policy on Israel and Palestine. To the point where you've arguing that Harris risks losing votes just for picking the wrong VP.

No, there's always some activists who manage to argue themselves into believing that there's "no difference" between the two "corporate" nominees of the two parties. Palestinian activists decide Biden is "Genocide Joe" for complicity on Gaza...and immigration activists decide that Biden is "Deporter Joe" for agreeing to the most stringent immigration bill in two generations. They both decide there's no difference between Trump and Biden on that issue, so they decide to "send a message."

Obama was no such thing. His DHS fudged the numbers to make it look like he was doing something so as to avoid any popular backlash.

No, they didn't. Obama vastly increased the numbers of deportations at the border. The exact same thing that conservatives are screaming about right now - deporting people at the border, not letting them into the country, not letting them wait for hearings. He did do a ton of stuff that immigration activists hated, because he knew he had to keep the numbers under control. The fact that he wasn't going after the specific subset of people who'd been here for years and years doesn't mean he wasn't deporting a ton of people - any more than the fact that Trump didn't try to deport DACA folks doesn't mean that he wasn't deporting people either.
