From Joe Klein's article on Gore as the nominee:
Pish-tosh, you say, and you're probably right. But let's play a little. Let's say the elders of the Democratic Party decide, when the primaries end, that neither Obama nor Clinton is viable. Let's also assumeand this may be a real stretchthat such elders are strong and smart enough to act. All they'd have to do would be to convince a significant fraction of their superdelegate friends, maybe fewer than 100, to announce that they were taking a pass on the first ballot at the Denver convention, which would deny the 2,025 votes necessary to Obama or Clinton. What if they then approached Gore and asked him to be the nominee, for the good of the partyand suggested that he take Obama as his running mate? Of course, Obama would have to be a party to the deal and bring his 1,900 or so delegates along.
And I thought Clinton was presumptuous for offering Obama veep?
