The Economy will be No.1, but housing will be a close second.
The Middle East and Energy will be tied for third.
Immigration will have to be dealt with but its going to be more a state deal I believe.
AZ started a new illegal immigration law in January and I will want to see what the 1yr anniversary has done.

Anyway you look at it, ( to quote Betty Davis) Hang on its going to be a Bumpy Ride
