I think a border fence is a bad idea too. It takes will. A fence in the middle of Big Bend is terrible and it would never ever pass Congress. Even if it did it's a bad idea.
No he's not. he supported Arizona in court and has said the federal government has no right interfering in a sovereign states decision on how to deal with the Federal failure to secure the border. He said he wasn't for it in Texas because he didn't want LEO's taking on that added responsibility. I will add that if you get arrested in Texas for anything and are illegal, you get deported.
Every candidate running is for "comprehensive immigration reform" Perry alone has said that is meaningless until you stem the flow at the border by securing it.
Bottom line, you do not require any other candidates to answer the same questions you demand Perry to.
