The major fault in the logic that you and others use is that these Mexicans force their way into the country. The reality is that the US lets them in, allows them in, welcomes them in.
And in more recent times, its not just Mexicans, they are from all over the world. There are 50,000 illegal Irish here.
There is a demographic reality that you can ignore if you want to, but it ain't going away.
I don't. Nor do I care what the country of origin might be - nor if they rode here on Air Force One at the invitation of President Carter. They are (how shall one say this???) ILLEGAL!!!.
I do hope that is clear to you. And I don't agree with your claim that "it ain't going away". There are geting to be a great many voters who are now realizing what the overly-liberal policies of selling our country short and giving it away are beginning to cost us. It must stop.
