It's a first for C-SPAN, so it should be fun, providing all the technical connections work.

We started working on it last week, have had a couple of run throughs, so today is the day. Around 7:50 p.m. eastern - 4:50 p.m. pacific, will be the first segment. The second segment will come at around 9:00 p.m. eastern - 6:00 p.m. pacific.

Of course, as these things go, all times are subject to change.

This is the first time C-SPAN has ever attempted video conferencing broadcast live, so I'm thrilled to be joining in to talk about the results from today's primaries. Unlike so many other talking heads, I'll actually be on as a declared Clinton partisan.

It's a big day. Can Obama close the sale? Will Clinton turn the race around? We shall see.
