One of the quieter stories that could have an impact as early as '08 is the new Maryland law regarding the electoral college.
"By terms of the compact, states agree to give all of their electoral votes to the national popular vote winner, not the winner in their own state. The compact would only go into effect once it was joined by states representing a controlling majority of the electoral college."
EDIT:
"Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors, equal to the whole Number of Senators and Representatives to which the State may be entitled in the Congress: but no Senator or Representative, or Person holding an Office of Trust or Profit under the United States, shall be appointed an Elector." Article 2 of the Constitution
In fact, we have an alternative method in place RIGHT NOW, as we speak:
"Two states do not elect the Presidential Electors as a single slate. Maine and Nebraska elect two electors by a statewide ballot and choose their remaining Electors by congressional district. The method has been used in Maine since 1972 and Nebraska since 1991, though neither has split its electoral votes in modern elections."
