Next, we go to Des Moines, Iowa where Sadhya Dirks of Iowa Public Radio joins us. Good morning.
SADHYA DIRKS, BYLINE: Morning.
MONTAGNE: And where did you start out this morning? I gather it wasn't Des Moines.
DIRKS: I was in a suburb of Des Moines. It's a more conservative part of Des Moines. It's Johnston, Iowa and I was at the Evangelical Free Church there, just talking to some voters and seeing what the turnout was like.
Both campaigns want to claim momentum heading into the final days of the campaign. This is especially true in battleground states like Iowa, where enthusiasm and voter turnout can make all the difference.
It's a common political metaphor — momentum — but is it a good one?
