Washington (CNN) Presidential candidate Pete Buttigieg will begin airing a new television ad in Iowa on Wednesday that takes aim at his Democratic opponents over health care, casting his plan as less restrictive than the "Medicare for All" proposal backed by Sens. Bernie Sanders, Elizabeth Warren and other Democrats.

The 30-second spot -- titled "Your Choice" -- heralds Buttigieg's "Medicare for All Who Want It" plan that would not force people onto government health coverage but instead would offer a public option for people who choose to enroll, a key distinction with the sweeping overhaul that would be instituted under a fully Medicare for All program.

"Providing every single American with quality health insurance isn't just my plan, it's our cause," Buttigieg says straight to the camera . "Now, I go about it in a very different way than my competitors."

The South Bend, Indiana, mayor goes on to tout how his plan "gives everybody access to Medicare. Everybody. But, if you're happy with the private insurance you've got my plan would let you stick with it -- if you want."

"Now, others say it's Medicare for All, or nothing," Buttigieg says, a not-so-subtle nod to Sanders, Warren and other pro-Medicare for All Democrats. "I approve this message to say, the choice should be yours."
