Saturday morning, from 10 a.m. to 12 noon Eastern, join Politics Nation on XM Radio's POTUS '08, when we'll tackle the week in politics. Listen free here (link about half-way down the page) as:

-- Wall Street Journal reporter Amy Choznik talks about life on a campaign, and the constant struggle to find a girlfriend or boyfriend in a tiny campaign office in Muscatine, Iowa. Later, we find out where in the world Mike Memoli happens to be today.

-- California Republican Rep. Kevin McCarthy isn't sitting back and waiting for the GOP to win a bunch of House seats, he's helping rebuild his beaten down party. Can a new group of Republican "Young Guns" be the answer the NRCC has been looking for?

-- And Democrats have expanded the House playing field, but they're still looking for ways to expand the Senate playing field. Could Elizabeth Dole be just the target they're looking for? State Senator Kay Hagan joins Politics Nation to tell us why she's the candidate to knock off a vaunted incumbent.

All that and a few surprises, we're sure, Saturday morning on Politics Nation, only on XM Radio's POTUS '08. Listen live, Saturday from 10 a.m. to noon Eastern and again at 7:00 p.m. Eastern.
