A contrarian view
Jay Cost says the party’s not quite over, and has some very interesting analysis of the demographics of West Virginia and Kentucky to back up the scenario he outlines:
What happens to “It’s Over” if Clinton pulls a 40-point victory in West Virginia on Tuesday, then follows it up a week later with a 30-point victory in Kentucky? If these states turn out in the same margins that states since March 4th have averaged, that would imply a net of about 290,000 votes for Clinton. That puts her within striking distance of a reasonable popular vote victory. “Over” will be over as we turn our attention to Puerto Rico.
There are good reasons not to take Puerto Rico lightly, even though the press has continued to do exactly that. I would note: (a) Puerto Ricans vote in large numbers (2 million in the last gubernatorial election); (b) Puerto Ricans have never had this important a role in United States presidential politics; (c) Puerto Rico’s politics is focused at least partially on how (if at all) to adjust its relationship with the United States; (d) Puerto Rico’s is an open primary, and the residents of the Commonwealth, who are United States citizens, do not see themselves as Republicans or Democrats.
The inference I draw is that Puerto Ricans could turn out in huge numbers. If they do, and they swing for Clinton in a sizeable way, the popular vote lead could swing, too. Add 290,000 votes from West Virginia and Kentucky to 250,000 votes from Puerto Rico, account for expected losses in Oregon, Montana, and South Dakota, and you get Clinton leading in many popular vote counts, some of which are really quite valid. If she has one of those leads when the final votes are counted on June 3rd, the race will go on to the convention.
Meanwhile, Charles Krauthammer, among many others, has an obituary for the Clinton campaign.
