The Affordable Care Act's future is in doubt, but that isn't stopping iowans from still being split on the issue. A "Des Moines Register/Mediacom Iowa Poll" found 46 percent say the law is a failure while 45 percent call it a success. The split falls among party lines as 89 percent of Republicans don't like the law at all while 83 percent of Democrats like it. The poll also surveyed certain parts of Obamacare and a vast majority of respondents said the ban on pre-existing condition discrimination should be kept, as well as medicaid expansion.
