On Wednesday, Tucker Carlson debated Massachusetts Institute of Technology Professor Jonathan Gruber, often considered one of the “architects” of ObamaCare, on the merits of the law and why Republicans want it repealed.

Carlson said that 20 percent of those on the insurance exchanges only have one coverage option, and listed a few criticisms that Americans have of the law.

“There’s been a lot of misinformation,” Gruber said, adding that some costs increases have been slower than before the law was passed.

“Americans just dont understand what this law has done for them,” he said.

Gruber said that the richest Americans and the youngest and healthiest may have indeed been hurt by the law, but the fact they often must pay more for healthcare has helped others who are less fortunate.
