Tune in for a special edition of The Race tonight on XM Radio's POTUS '08 as Real Clear Politics guest hosts. Join Politics Nation from 7 p.m. to 9 p.m. as we tackle the hot issues of the day in politics. Listen free here (link about half-way down the page) as:

-- Reid Wilson and guest host Kyle Trygstad dissect the race, the polls and the status of Barack Obama and Hillary Clinton as they battle for votes in Indiana and North Carolina. We'll hear from each of the candidates as well, with audio from today's events in both states.

-- In the second hour, we'll dive deeper into Indiana with pollster Ann Selzer, whose polls this year have nailed margins and turnout figures in Iowa and Michigan. Her new poll sheds light on the race in Indiana, which may be much more wide open than we all think.

-- And, as a special treat, an exclusive interview with Democratic Congressional Campaign Committee chairman Chris Van Hollen, on his party's outlook in the 2008 Congressional elections, upcoming special elections in Louisiana and Mississippi, and much more.

All that and a few surprises, we're sure, tonight on The Race, only on XM Radio's POTUS '08. Listen live, tonight from 7 p.m. to 9 p.m. Eastern.
