Iowa!

This week, Karin speaks to Pat Rynard, Managing Editor of the Iowa Starting Line blog, about what is happening on the ground in this vital state. He'll give us a sense of what the candidate rallies and events feel like on the ground, why some candidates seem to be taking off there while others are slow to catch fire, and talk us through the pluses and minuses of having Iowa go first in the first place. Also this week, we'll cover the primary news, paying particular attention to the exit of Kamala Harris from the race, and asking where her supporters might go from here.
