Kathy Sullivan alerted us a couple of weeks ago to the GOP-sponsored initiative in California to allocate its Electoral College votes by Congressional district, rather than "winner take all."
The New Yorker wrote about the effort. Maine and Nebraska (and no other states) have used this method for decades; Colorado considered it in a ballot initiative in 2004. If California adopted "proportional" EC voting, it would (based on historical voting patterns) give the GOP another 20 votes or so.
Thanks to DCDemocrat of DailyKos for pointing this out. Article II, Section 1 of the US Constitution states:
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.
California can use its absurd initiative process all it wants for state matters -- but it cannot use it to take power away from its elected legislature that was given to it by the federal Constitution.
Two caveats: a) I Am Not A Lawyer; and b) the current SCOTUS just might ignore the clear words of the Constitution if it helps the GOP.
