Of course it's an excuse, ANOTHER excuse, to bash President Bush, whose position has not changed since he ran in 2000.
Look at the border towns and check their "elected" US Representatives!
My former Congresswoman was the democrat Susan Davis of San Diego, a border town! She unseated GOP Brian Bilbray and has held the seat ever since.
You'd think, that border towns would elect congress persons who campaign on sealing the vorders etc., but that's not the case.
Much easier to blame POTUS, when in fact, his position has been clear for years.
