LENEXA, Kan. -- After weeks of speculation and days of intense rumors, the answer to who Democratic presidential candidate Barack Obama would name as his running mate may have come down to a bumper sticker printed in Lenexa.

KMBC's Micheal Mahoney reported that the company, which specializes in political literature, has been printing Obama-Bayh material. That's Bayh as in U.S. Sen. Evan Bayh of Indiana. Word leaked out about the material as it was being printed up by Gill Studios of Lenexa. The Obama campaign had said it would make the announcement by text message on Friday.

Gill Studios, which invented the bumper sticker, would not confirm information about the material. They would not deny it either.

"We're very disappointed that you would spread this rumor," Gill Studios President Tom Carrico said.

"You didn't print it here?" Mahoney asked.

"I didn't say that. But I'm very disappointed that you would come out and interview us and ask for confirmation and we said we would not confirm," Carrico said.

"Or deny," Mahoney said.

"That's correct," Carrico said.

Mahoney reported that at least three sources close to the plant's operations reported the Obama-Bayh material was being produced.

Bayh has a reputation as a fiscally conservative Democrat. Bayh endorsed Hillary Clinton and it is believed that he could help the Obama ticket by delivering a key battleground state.

Obama has arranged a joint appearance for Saturday with his running mate at the state Capitol in Springfield, Ill.
