I don't really care what he does with the people here now, but the freaking border needs to be secure. I don't even care if we let in everybody that wants to come in, but they shouldn't be able to do it by simply walking across the border. It's not good for them and it's not good for us.
That is much easier said than done. What really needs to be done is to strictly enforce employment law and make E-verify a requirement. Making sure small businesses and contractors are following this law is the big challenge. If jobs still exist for illegal immigrants, they will continue to come. I agree with all that.
We waste use resources inefficiently all the time. The couple extra billion it would take to properly secure the border is nowhere near the most wasteful way we spend money. Clearly the border can be more secure than it is now.
