It's still a losing issue for Democrats as most voters don't care about statistics. It's more about vibes, feeling and perceptions. Basically the same with studies showing the US economy would be doing worse without immigrants.
What would help is Biden hammering Republicans on a border security deal and try to do more via executive action. In the long run, only comprehensive immigration reform can address or resolve the issue.
The problem is that immigration massively surged under Biden's watch and was at much lower levels under Trump's watch.
