A week ago, Bob Kerrey -- former governor and Nebraska senator -- arrived at the University of Nebraska Medical Center for a media blitz. A week later, he hasn't yet decided if he'll run for Ben Nelson's seat.
"No decision yet," is what Kerrey wrote in an email to Channel 6 News.
Announcer for a commercial from the National Republican Senatorial Committee: "Think Ben Nelson was bad..."
Outside money bundled without the endorsement of any candidates quickly shifted from Nelson to Kerrey.
Announcer in television ad: "Big Apple Bob Kerrey. Perfect for New York."
"We haven't really seen it here. These preemptive strikes," said Dr. Loree Bykerk, political science professor at UNO. "There are people out there closer to it than I am that are putting money into it already and they're not doing it just for the fun of it."
Announcer in Americans for Prosperity commercial: "After more than a decade away, Bob Kerrey is back pushing his east coast liberal agenda."
Imagine what the airwaves will look like if Bob Kerrey gets in.
It's a race Senator Nelson believes would cost upwards of $40-million -- twice as much as his record-setting last race.
While opponents hammer Kerrey for being away from Nebraska for so long, some things have changed from his last election in the 90's.
"It is also true that registration is more republican now than when Kerrey was successful here," said Bykerk. "I think he's coming in as less than the favorite. If he comes in."
So who runs if Kerrey doesn't? There's isn't a lot of time to mount a campaign.
State lawmaker and attorney Steve Lathrop, Lincoln mayor Chris Beutler, and Kim Robak, who served as lieutenant governor under Nelson.
Out of the three, Beutler said he's happy being mayor.
