They ALL have to go back.
It is only trolls like you who insist that it is only possible to solve one problem at a time, and further, deny the existence of one of the problems.
In the last 20 year, Republicans have not done one thing to stop illegal immigration. In fact they've made it worse.
What makes you think the Republicans can stop any problem?
I am merely saying, go after the low hanging fruit. If the Republicans can solve illegal immigration, legal immigration will be no problem. But if they lose focus, they won't get anything.
What makes you think they can do everything at once? They can't even have a Republican as House speaker.
Did you see the 2024 election? Tens of millions of people voted for Republicans to end illegal immigration. Many of them voted for Republicans for the first time.
If they see Republicans do nothing about illegal immigration, or fumble the ball, what do you think will happen? They will NEVER vote Republican again.
A county in Texas that is mostly Hispanic and borders Mexico voted overwhelmingly for Trump. The first time for a Republican. If those people see the Republicans do nothing about illegal immigration, they will learn a lesson to never vote for a Republican again.
Republicans have a chance to either look in an electoral change in their favor, or lock in an electoral change in the Democrats favor. The #1 issue is illegal immigration. More important than wokeness, trans, whatever.
Anything that distracts from that is helping Democrats. If the Republicans win on that issue, they will have the opportunity to get a lot more accomplished. If they don't, they may not even be the 2nd party in U.S. politics.
Only trolls try to downplay the importance of illegals for this country.
