The US Senate may soon be holding a hearing on a measure that would propose a national regional rotating primary system:

The Senate Rules and Administration Committee will hold a hearing Wednesday on a bill authored by Sens. Amy Klobuchar (D-Minn.) and Lamar Alexander (R-Tenn.) to create a rotating regional presidential primary.

Under the “Regional Presidential Primary and Caucus Act of 2007,” beginning in 2012, a region-by-region primary would be initiated, taking place after the Iowa caucus and New Hampshire primary. The four national regions (West, Midwest, South and East) would rotate going first each cycle, with votes occurring on the first Tuesday of each month running from March to June.

So Iowa and New Hampshire will still get to go first, and then the differing regions will have a shot.
