...Concern over the expense of dealing with illegal immigration is certainly not unique to the Republicans. What is different, between the two parties, is the perceived urgency of the problem. Many of the current Republican candidates are seeking support from southern / southwestern voters who deal with the issue on a daily basis. With family down in Yuma, AZ, very close to the border, I hear weekly about the problems they are having with illegal immigrants, particularly in regards to drugs and violence. Many of those voters are simply infuriated with the refusal of the federal government to deal with it.
