Hillary Clinton has a new radio ad in South Carolina, aimed at a key constituency in the state — veterans. In the new ad, Hillary pledges more support for veterans' health care, and declares that the government has been eager to send troops to Iraq but not eager to take care of them when they return.

In addition to the battle between Hillary and Obama for African-American voters, veterans could also turn out to be an important demographic for both parties' primaries — and a female candidate might have to work extra hard for their support.

The ad is available after the jump.
