IIRC, you once posted that immigration as an issue wasn't that important. What made you change your mind?
I don't remember the exact question or my exact answer, but a couple two or three years ago, someone asked me something to the effect of please list the Republicans in congress who were doing something about illegal immigration? I admitted that I did not know. It wasn't a hot issue to me at the time and I wasn't following who was doing what about illegals. It has become more of an issue with everyone now, and I truly believe it will be a key issue in the coming election. If a candidate gets it wrong on the war or on national security, including border security, then he/she will have big problems getting the nod in the primary or winning the presidency in the general, IMHO.
And should the wrong man or woman win the presidency, we're all going to pay the consequences. The nation will be secured now, or in January 2009, or after a whole lot of people die unnecessarily. Makes sense to secure the borders as soon as is humanly possible.
