Obama deported more illegal immigrants than George W Bush and Donald Trump combined. Biden deported more illegals in his first 18 months than Trump did during his entire term.
Democrats being “weak on immigration” is nothing more than a racist dog whistle to stir up GOP voters.
Nobody wants illegal immigrants pouring over the border. That being said, some of us are a lot more understanding about it than others, because there would be a lot fewer people trying to cross if the CIA didn’t spend the last 60 years deliberately destabilizing South American governments. Fortunately, that’s not how most illegals get here. Most of them just overstay their visa after it expires. Which means that most of the time, deporting illegals involved lots of boring paperwork and happens one person at a time. There’s no drama in it, so it doesn’t really make the news like immigrants at the border do.
Democrats understand that simple fact. Republicans don’t.
