Hello and welcome to this late political gap fest.

I'm John Dickerson here with Emily Bazelon and David Plotz.

Today we're going to talk about the Pennsylvania primary and politics.

We're also then going to talk about world food crisis.

And then the third topic is going to be the autism pander.

We're going to come back to politics how the candidates are all pandering on the question

of whether vaccines lead to autism.

And cocktail chatter.

And then we're going to end.

All important cocktail chatter.

If vaccines lead to cocktail chatter, which in this case it will.

David, you have in the past, when we've talked about

the superdelegates versus the pledge delegates and the fight that's inevitably going to arrive

in the Democratic Party, you've stuck up for the superdelegate system. So what I want to ask you

is in that context, did the superdelegates get more data for their argument if they're going to

overthrow the momentum that Barack Obama has among the

pledged delegates.

From the Pennsylvania, from Hillary's a nine-point Pennsylvania victory.

Thank you, yes.

9.2, yes.

Well, I mean, it's another point of information.

It's more, it's another data set.
