UPDATE 8:45 p.m.: The Star's Aaron Barnhart, on his TVBarn blog, on KMBC scaling back its original story. 

UPDATE 7:30 p.m., from the AP:  

"Officials said the Obama campaign had taken the trouble to print material bearing the names of several potential ticketmates — thereby minimizing the significance of a report that a printing company in Kansas was churning out signs bearing Bayh's name.

Obama told reporters on Thursday he had made his choice, and aides used the prospect of a text-message announcement to try and attract additional supporters by soliciting their cell phone numbers and e-mail addresses.

Even that became occasion for intrigue.

Late Friday, several officials said the text message announcement would be distributed Saturday morning, a few hours before a scheduled rally at the Old State Capitol in Springfield, Ill., where the Democratic ticket would appear for the first time." 

KMBC is reporting that a Lenexa printer may be cranking out Obama-Bayh (as in Sen. Evan Bayh from Indiana), suggesting the campaign has sprung a leak on the closely held veep choice.

An Indiana television station, however, is noting that they printed up tee-shirts with a number of combinations, without being told which one to start producing in mass numbers.

Here, we talked to Tom Carrico, the president of Gill Studios Inc. in Lenexa, to check. He's coy.

Yes, he says, his firm has gotten artwork for multiple Democratic vice presidential picks in recent weeks. No, they're not printing Obama-Bayh bumper stickers now. Have they printed them recently? He won't say.

The TV station's web site shows what looks to be an Obama/Bayh '08 bumper sticker, but doesn't explain the source or even explicitly claim it to be the work of Gill Studios. Could be legit. Could be one of the many forms of artwork for potential bumper stickers the firm has received.

It would fit with this tidbit from The AP:

"Tucked away in one corner were thousands of lightweight rolled cardboard handles, meant to allow delegates to wave signs bearing the names of the ticket — once the identity of Obama's running mate was known."

And KMBC's Mike Mahoney says he has three sources saying they're being shipped to Denver. There's a convention of some sort about to start in Denver. 

In any event, Carrico said it doesn't do business directly with the campaign. Rather, distributors order and purchase from Gill Studios. So that would mean that for the bumper stickers to be a sign of a certain choice that the campaign would have had to told its consultants to start getting placards and such, and that those people would have to spill something to printers like the one in Lenexa.
