Despite Obama’s so-called insurmountable lead in delegates, they are splitting them about 50/50. There’s no way that Obama or Hillary can accumulate the required 2100 or so delegates it would take to out-right claim the nomination.
It’s going to come down to the super delegates, uncommitted delegates.
That means the Dem Convention is going to decide. I think they’ll choose a Clinton/Obama ticket, the thinking being that Obama is young and inexperienced, and the VP slot will give him the gravitas for either the 2012 or the 2016 campaign.
Like I said, Pennsylvania will decide it.
