The "I never was a maverick" John McCain wants to build the fence. Three years ago he was calling people who made statements like this racists. But that was before he had to pretend to be a Republican for a contested primary.
Why would Senator McCain embarrass himself like this? For senators, 70 is the magic number. If your senator is 70 years old, the only way he is leaving is in a box. And if you have to change parties (80 yr-old Arlen Spector) or legislate from a nursing home (92-yr-old Robert "Sheets" Byrd) you will puke up whatever principles you had in order to save your spot in D.C.
