Interesting in the same sentence you directly foot gunned yourself.
First of all, the bipartisan bill would have de-facto ended catch and release due to significantly ended "Catch and release" or Notice to Appear since there was now sufficient capacity to adjudicate.
You are correct 10 million were not substantially deported because a majority of them never entered at all that 10 million figure is just a downright lie. Based on the data from Title 42 expulsions around half of that 10 million were people sent back.
"The bipartisan bill would've still allowed in thousands of people per day."
Funny because if we take your (lies) about 10 million the legislation would have cut that down by 80% on just the caps alone. Increase in adjudication and the end of catch and release (if we assume all of the 2 million getaways are entirely dishonest) then it would be less than 10% of that figure.
Perfect is the enemy of good or something like that.
How many encounters are there now? DHS says it's a historical low with a 95% reduction. How many people are paroled or given NTA releases now? Sources suggest 0 in the first year. What's the asylum grant rate now? Sources suggest it's about 7% now as opposed to 65% or higher previously.
The bipartisan bill was full of loopholes and it only triggered when border crossings exceeded certain rather high thresholds. Do you realize that? It wasn't comprehensive at all. Here is an example of a loophole: "While the president’s parole authority would be narrowed, he or she would retain the power to parole entire classes of migrants and would have greater authority to do so at airports." (https://digital-release.thehill.com/?p=4447957). So this assumes Biden and Mayorkas were genuinely trying to fix the problem all of a sudden in 2024 as they were facing an election. Why would we want to codify allowing in a certain high number of people along with loopholes when we could just replace Mayorkas and Biden?
The thing is that Mayorkas WANTED the border to be open. This wasn't a mistake. It's an unofficial policy that you're dancing around. I am not interested in stupid Trump vs Democrats or GOP vs Democrats bullshit. There's a substantial nnumber of people who want large scale immigration and a substantial number who don't so all this legalistic bickering is just window dressing for this issue but don't try to pretend that it's universally the moral or democratic norm to have open borders.
