This does not bode well for fall if, as still expected, Obama is the nominee.
And if you want some poll crunching, Obamaist Kos analyzes Obama-Clinton strengths and weaknesses in Kerry states and the big three -- Pa., Ohio and Fla. Pitfalls for both, Kos notes, though he sticks with Obama.
If I may say again: this is why the nomination shouldn't be decided simply by who's ahead in pledged delegates. There are many factors to consider. The deciding delegates may well decide that those factors favor Obama. (An influential one from Washington (he formerly backed Clinton), with roots in Indiana, did just that today.) But let's play out the primaries and the flavor-of-the-day hot button story, take a deep breath and then let the final delegates decide based on ALL the evidence.
