I notice from the article that Ohio (2004 election) is still a sore point for the Democrats. Ohio, so far, hasn’t introduced such a bill.
Before the election it looked like Ohio would be about as close as Florida in 2000. After the election the 118,775 vote difference (the MSM like to quote 60,000 switches rather than nearly 120,000 difference) was beyond the Dems' creative counting plans so the teams of lawyers ready to come in just didn't show up. A 2% win by Bush was too much to change through post-election trickery.
In 2008, the National Popular Vote bill was introduced by Representatives Vernon Sykes, Barbara Boyd. Edna Brown, Tom Letson, John Otterman, Michael Skindell, and Sandra Williams -
HB 524.
