Barack Obama can bring an end to the impasse with Florida and Michigan with a simple compromise measure: seat Florida and Michigan's delegates as is under one condition: all of Michigan's "Uncommitted" delegates become pledged to him. Given that Sen. Clinton was the only major candidate on the ballot, it only strikes me as fair that the people who showed up to vote against her have their votes count, as well. Seems simple and fair enough, except for one problem for Sen. Clinton: seating Michigan and Florida "as is" only nets her a 44 delegate gain, which chops Obama's pledged delegate lead from 169 to 125. She would need to carry Pennsylvania with 95% of the vote to overcome that lead (there aren't enough delegates in Pennsylvania for her to overcome his present pledged delegate lead), or else carry every remaining state (including Pennsylvania and all the way up to Puerto Rico) with an at least 64% of the vote. That's with Florida and Michigan added to the tally. Without them? She has to win every remaining state with at least 69%. In other words, Florida and Michigan don't aid her cause as much as she'd like us to believe, unless she insists on some "winner take all" standard for those states which hasn't been applied to any other state and she's not in a position to demand. Absent that, adding Florida and Michigan moves her chances from just this side of impossible to... just this side of impossible.
Obama should agree to seat Michigan and Florida (with the one caveat I specified above regarding uncommitted delegates), then he should show this math to the press and call on Sen. Clinton to bow out gracefully. If she won't, then the remaining superdelegates need to put this one to rest. It's all over but the crying, but if I know Sen. Clinton, there's still a lot of that to be had.
