I would definitely say that the progressive caucus inside the Democratic party is pro-immigration. If it were not for the two party system, this would be its own party. Regrettably this sub-group does not have a ton of influence on their party’s policies, but their influence has been growing for sure since 2018, getting almost a 100 seats in this years mid-term election. Not all districts have the option of voting a progressive (which most likely happens in a democratic primary vote), and quite a lot of times a progressive actually looses to a moderate (or even a conservative in the case of Cisneros vs. Cuellar in TX-28). But my feeling is that the progressive caucus has not stopped growing, my hope is that this will result in a significant reform in the kind of immigration policy the democratic party endorses.
