Migrants Rushing to Arizona

Powerline has this post today about a Macleans story titled: "Migrants rush to Arizona border anticipating passage of guest-worker plan."

In anticipation of a guest worker program, people are hurrying to get across the border so they can possibly be included in whatever program Congress finally works out. The Macleans article also states:

Many of the migrants also are being driven by a desire to get into the United States before the likelihood that legislators further fortify the border.

Indeed.

Let me pose a question here. Why are they rushing to Arizona and not, say... San Diego? Could it be because San Diego has a fence?

Note to lawmakers: Maybe fences really work.

Build the fence.
