KANSAS CITY, Mo. (AP) — A new Gallup poll shows Kansas is the only state in the nation to see a significant increase in its uninsured rate this year, while states that adopted parts of the Affordable Care Act have seen the largest declines. The Kansas City Star reports that the adult uninsured rate in Kansas rose from 12.5 percent last year to 17.6 percent during the first half of this year, giving it the seventh-highest uninsured rate in U.S. Missouri's uninsured rate remained essentially flat, with 15.2 percent uninsured in 2013 and 15.1 percent uninsured this year. Research director Dan Witters did not offer an explanation for the growth in Kansas uninsured. A spokeswoman for the Kansas Department for Aging and Disability Services says the ACA was directly responsible for the state's spike.
