If Senator Nelson really wants to do something he should get really tough; down and dirty tough. His fence building will go on through out the election year make it sound like he is doing something when he ought to be demanding the Death Sentence for all Drug Dealers. Just more political rhetoric
"Putting up a fence will have little effect and cost the taxpayer jillions. "
Not "jillions", about $5 billion (meaning $2 million a mile, a reasonable estimate). In the entire scheme of things, this is a drop in the bucket. And what do you mean it will have "little" effect, that's just patentedly untrue.
"Those who want in will simply fly over it"
We aren't trying to stop migratory birds...or have Mexicans "evolved" to be able to fly?
