South Dakota's 2014 U.S. Senate race has been called one of the biggest in the country and right now polling shows former Governor Mike Rounds holds a big lead.
But Rounds is preparing for other Republicans to challenge him in a June primary before he even gets to the general election. And Democrat Rick Weiland, who will likely run against Rounds in November, says he's going to give Rounds a run for his money.
"We've been running against big money and the special interests they represent and I think people are connecting with that message," Weiland said.
"It's a long way to go. It's a marathon and we're just not taking anything for granted," Rounds said.
Despite a Nielson Brothers Polling survey that shows Rounds has a two-to-one lead over Weiland, Rounds is anticipating a primary.
A possible challenger, Sioux Falls Doctor Annette Bosworth, says she's getting close to making a decision.
"The missing piece is the money. I mean Mike Rounds says outwardly $9 million," Bosworth said.
Bosworth has visited a dozen communities in the last few weeks to gauge interest in a run for the Republican nomination but says Rounds' fundraising goal of $9 million is one of the next hurdles in making up her mind.
"I don't want money to be what makes my decision but I'm not a fool. This is a game of politics and you have got to have support and the only way that translates to the larger audience is with George Washington," Bosworth said.
Weiland is also pointing to the multi-million dollar campaign Rounds plans to run as a reason why he is the better choice.
"So much of what has gone on in Washington has led to dysfunction, bad public policy and I really do believe it has a lot to do with how much big money influences public policy," Weiland said.
Rounds says while the money is coming in and the support is there so far, he's still working to campaign in communities across the state.
"We're felling good about the projection of the campaign right now but it's a long way until the end and we're just going to focus on the original game plan," Rounds said.
Bosworth says she plans to spend another week touring South Dakota before making any decision.
Both Rounds and Weiland say they hope to visit every community in the state.
