"I hate what Obama's doing to the country, but if we don't win, it's just all talk. I can win," U.S. Senator Lindsey Graham told supporters Saturday morning in Goose Creek, laying out his plans for immigration, health care and economic reforms.

Graham spoke at American Legion Post 166 to a crowd of more than 250, a week and a half before the GOP primary that will determine whether he can run for re-election this fall.

"I get the nomination, the Democrats go somewhere else because they know they can't beat me," he said.

Republicans should organize a document for "unity of purpose," he said, and put at the top of the list support for the Keystone Pipeline and domestic oil.

And immigration is an economic issue, he said, so efforts should be made to make it easier to verify legal working status.

Graham said the Department of Veterans Affairs' recent scandal "breaks your heart" and indicates what will happen if all health care is turned over to the government.

"Obamacare is the VA on steroids," he said. "If we don't turn this around quickly, then everybody in America is going to be in the same boat as the veterans."

Instead, he said, "How about medical malpractice reform, so the doctor can actually work on you without worrying about being sued every five minutes?"

And terrorism is still a real threat from several parts of the world, he added.

"If you don't think we're in a war with radical Islam, then don't vote for me, because I do," he said.

Graham also said Republicans should be working on winning back minority votes.

"We've got a branding problem," he said. "Minorities for some reason, and we've got to think of why, feel uncomfortable with us but not with conservatism. We're going to fix that."

Graham faces six opponents in the Republican primary: Columbia pastor Det Bowers, Spartanburg state Sen. Lee Bright, Easley businessman Richard Cash, Orangeburg attorney Bill Connor, Columbia attorney Benjamin Dunn and Charleston businesswoman Nancy Mace.

All but Dunn participated in a forum in Columbia Friday.

The primaries for both parties are June 10.
