A July 28 poll by Survey USA for KWCH in Wichita reveals a couple of interesting things about President Barack Obama in the state.

It isn't a surprise that he's unpopular -- he's got a 36% approve / 61% disapprove rating in largely Republican Kansas.

But look at this:

Income less than $40K: 33% approve 63% disapprove

Income more than $80K: 37% approve 60% disapprove

Age 18-34: 28% approve 69% disapprove

Age 35-49: 40% approve 57% disapprove

Age 50-64: 40% approve 55% disapprove

Age 65+: 38% approve 59% disapprove

The best guess? Unemployed or underemployed people are most likely to be 1) young and 2) poor.

If Obama is in similar trouble in swing states, he's in -- well, trouble.
