Kansas City, Mo. ? It’s being billed as one of the largest free clinics in the nation.

Kansas City’s Bartle Hall was the site Wednesday and today for a free medical clinic for the uninsured. It’s one in a series of clinics in different cities put on by the nonprofit National Association of Free Clinics.

The group says the clinics are nonpartisan, but the effort is widely seen as a way to pressure moderate Democrats into supporting their party’s efforts to reform health care.

Previous one-day clinics in Houston, New Orleans and Little Rock drew well more than 1,000 patients.

The NAFC says an estimated 1,200 volunteers are taking part in the Kansas City event, including doctors, nurses, dental professionals and others who will provide care.
