You two are on to something.

Repubs will use the SCOTUS killing DACA to push some abusive shit.
I hope they don't use BC to bargain because the calculus will get ugly.

I don't know if the Dems would save us in exchange of Birthright Citizenship.

Saving BC is a greater cause to them than saving us.
Birthright Citizenship is a baby factory of Dem voters. It's what turned Cali into solid blue and made some border states competitive.

BC gives them millions of brand new voters. They will not sacrifice future millions to save a few thousands of close to middle age potential voters in the present.
