How will Gaza play in the 2008 campaign?

The Times of London has a great story on how Hamas secretly brought down the border wall between Gaza and Egypt:

[A] Hamas border guard interviewed by The Times at the border today admitted that the Islamist group was responsible and had been involved for months in slicing through the heavy metal wall using oxy-acetylene cutting torches.

That meant that when the explosive charges were set off in 17 different locations after midnight last night the 40ft wall came tumbling down, leaving it lying like a broken concertina down the middle of no-man's land as an estimated 350,000 Gazans flooded into Egypt.

I was watching footage on Al Jazeera today, and it was like nothing I've ever seen—thousands of Gazans streaming across the border in search of Egyptian bargains and a little breathing room.

I'm sure Lou Dobbs has already thought of this, but I wonder how this kind of imagery is going to play in the immigration debate in the United States. I'll be on the lookout for statements from the candidates on this, if they haven't made them already.
