Have you ever wondered what would happen in this country if only women (and not men) were allowed to vote? Here's how the electoral college changed between Bush/Gore and Bush/Kerry between the two elections. (For the old numbers I'm going by the change in Bush's percentage. This screws up the Nader factor a bit, so take this with a grain of salt.)

Old numbers:

Bush Wins 154 electoral votes: AK, GA, ID, IN, KS, KY, LA, MS, MT, NE, NC, ND, OK, SC, SD, TX, UT, WY
Gore Wins 366: AZ, CA, CT, DE, DC, FL, HA, IL, IA, ME, MD, MA, MI, MN, MO, NV, NH, NJ, NM, NY, OH, OR, PA, RI, TN, VT, VA, WA, WV, WI
Too close to call 18:AL, AR, CO

So Gore wins the female electoral vote: 366-154 with 18 too close to call.

New numbers:

Bush Win: AL, AK, AZ, AR, CO, FL, GA, ID, IN, KS, KY, LA, MO, MS, MT, NE, NC, ND, OK, SC, SD, TN, TX, UT, WY, WV
Kerry Win: CA, CT, DE, DC, HA, IL, IA, ME, MD, MA, MI, MN, NV, NH, NJ, NY, OR, PA, RI, VT, WA, WI
Too close to call:NM, OH, VA

So it'd be a cliff hanger. Bush at 236, Kerry at 264 with 38 electoral votes still up in the air.

That's where the election changed. From a Gore blowout among women, to a Bush/Kerry virtual tie among women.
