"Democratic Party rules say states cannot hold their 2008 primary contests before Feb. 5, except for Iowa on Jan. 14, Nevada on Jan. 19, New Hampshire on Jan. 22 and South Carolina on Jan. 29.

The calendar was designed to preserve the traditional role that Iowa and New Hampshire have played in selecting the nominee, while adding two states with more racial and geographic diversity to influential early slots.

Democratic National Committee officials have threatened to strip Florida, which has moved to Jan. 29, and Michigan, which has moved to Jan. 15, of all their convention delegates."

I can't find a record of NH moving up. MI moved ahead of NH.
