ryan, what's going on behind you? >> reporter: it's a beautiful day here in council bluffs. paul ryan expected to hold a rally here in about 40 minutes or so. and a lot of people around the country are probably wondering why so much attention why do these politicians pay so much attention to iowa? candidates come here to test the waters for a presidential run. >> the president has a rather comfortable lead here, an eight-point lead here in iowa, a six-point lead up in wisconsin, if the president is able to hold those two states, it really makes the pathway to 278 much easier for him. they spent a lot of time here and i expect in the next 16 days will probably come back to iowa,
