No, that's horrible politics and is quite literally a big part of why Dems lost in 2024 (and lost in many prior elections). Telling voters "Trump is right about immigration and the border and how important it is, and Dems are weak pussies on it, and I will be like Trump on it but just a little nicer" is just telling undecided voters to vote for Trump. Biden and the Dems were actually very anti-immigration during his administration. That's why the public shifted so strongly against immigration generally between 2020 and 2024, and look what good that did. Trump's overreach provides another opportunity for Dems to embrace immigration as a fundamental part of the American dream. Legal immigration used to be pretty popular even among white Americans and it could be again.
If Dems want to try to appeal to some of the racists on immigration, they should yell about how Trump cut a deal with the cartels and brought a bunch of high-level cartel guys into the country and that they'll send those guys back.
