Just over a year ago, we announced that we would come to Pittsburgh for our fourth annual Netroots Nation gathering. Since then, a lot's happened in our host state -- the Steelers won the Super Bowl, the Phillies won the World Series, the Pens won the Stanley Cup, the G-20 booked Pittsburgh as its host city, a U.S. Senator switched parties and a U.S. Representative quietly announced that he intended to run for Senate.

As local residents and interested citizens across the country turn their eyes to what promises to be the most-watched Democratic primary of 2010, we thought it only natural to provide our attendees with an opportunity to interact with Pennsylvania leaders Rep. Joe Sestak and Sen. Arlen Specter.

On Friday, August 14, Sen. Arlen Specter and Rep. Joe Sestak will join us in Pittsburgh to take questions directly from you.

The Netroots Nation Pennsylvania Leadership Forum, scheduled for Friday morning at 11 a.m., will give you and your fellow attendees an opportunity to engage both leaders in substantive discussion about issues of the day.

Rep. Sestak and Sen. Specter will each participate in an interactive session moderated by Pennsylvania blogger Susie Madrak and The Nation's Ari Melber. Much like our Presidential Leadership Forum back in 2007 and our Ask the Speaker session last July, each participant will be asked questions solicited online in advance, as well as from the audience.

As The New York Times reported, Netroots Nation is "becoming as much a part of the Democratic political circuit as the Iowa State Fair." So as speculation builds around the 2010 Senate primary, we hope you'll join us for a unique opportunity that reflects the Netroots spirit of grassroots democracy.

Netroots Nation is August 13-16 in Pittsburgh. If you haven't registered, there's still time. Tickets are just $275 (but going up soon), so register today.
