(WICHITA, Kan.) -

Most Kansas politicians fought hard against the Affordable Care Act.

Now, some of them may be rethinking after a new nationwide survey.  Based on the Gallup Well-Being numbers, Kansas was the only state to show a significant increase in the number of uninsured people since the law took effect.

The phone survey was based on a sampling of about 850 Kansans who were asked "Do you have health insurance?"

The results were eye opening.  Kansas went from 12.5 % uninsured last year to 17.6% in the first six months of 2014.

Every other state either reduce its uninsured numbers, held steady, or had increases that were negligible, less than 1%.

If in fact, Kansas has five percent more uninsured, critics would point to the state's  decision not to expand the Medicaid program under the law, a move intended to qualify more poor people for coverage.

However, 23 other states chose not to expand Medicaid and none of them saw increases like this.  Iowa did expand Medicaid and it had the second highest increase in uninsured at .6%.

"We were struggling to try and figure out what in the heck was going on because I just can't believe we're that much of an outlier," said Kansas Insurance Commissioner Sandy Praeger.

According to Praeger, it's "virtually impossible" to get the actual number of uninsured Kansans. She thinks the survey results are an "anomaly" and said Gallup told her it too was puzzled by them.

Still, Praeger wouldn't be surprised to see "some increase" in the uninsured numbers because of the state's failure to expand Medicaid.  She says another survey needs to be done at the end of the year.

"And if it's still high then we to start looking at what are some of the reasons that people in Kansas are not getting insured," said Praeger.

The Kansas Department for Aging and Disability Services was also surprised by the survey results. 

"You cannot produce a reliable picture of healthcare in Kansas from one poll," spokeswoman Angela de Rocha wrote in an email.

De Rocha also tried to debunk the Medicaid theory by pointing out there are "approximately" 424,000 Kansans on Medicaid this year, compared to 398, 924 in 2013.  That's an increase of greater than 6%.

"Any reported increase in the uninsured most likely is driven by the increasing costs and lack of access to private insurance that are a result of the Affordable Care Act mandates and requirements," de Rocha wrote.
