They may be long gone from Northwest Indiana, but their bills are not.

After their weeks spent stumping through the region before Indiana's primary, Democratic presidential candidates and U.S. Sens. Barack Obama and Hillary Clinton left some as-of-yet unpaid bills for rent or donation agreements.

Federal campaign reports filed last week show Obama lists a little more than $2 million in debts through April, none in Indiana.

Clinton owes $19.5 million in debts through April, about half of which she lent her campaign. Clinton lists $33,664.46 in Hoosier debts, almost $5,000 of which is owed to school districts in Indianapolis and Muncie.

Not included in the recent federal reports are debts the candidates owe in Northwest Indiana, which vary across the region, a Times analysis shows.

Both candidates owe fees to local schools.

Obama owes the Gary Community School Corp. for his April town hall meeting at Roosevelt High School and Michelle Obama's May visit to West Side High School. Gary school officials said they still were tabulating the precise amount Wednesday.

His campaign has paid the $726.12 it owed for an April Michelle Obama stop at Merrillville Intermediate School.

The Clinton campaign already paid an $800 deposit it owed for an April Hillary Clinton visit to Washington Township Elementary. But it owes another $1,000 for custodial work there, district Business Affairs Director Rodger Smith said.

Smith said he had "no idea" when his district would be paid.

"Probably not for a while," he said.

Clinton also owes $2,275 to the School City of East Chicago for her April 25 visit to E.C. Central High School.

The district gave the campaign an invoice on the day of the event, Schools Treasurer Frank Ramirez said.

"I'm expecting payment," he said.

So, too, is the Southlake YMCA in Crown Point, which hosted Bill Clinton on May 1. Executive Director Phil Mallers said the campaign is expected to donate at least $1,000 to its before- and after-school programs, which Mallers expects to receive within the next couple of weeks.

"That's a lot of money for us," Mallers said. "It really goes a long way."

Munster Steel President Jeanne Robbins would not provide details on any rental agreement for Obama's May 2 speech at the plant.

"That information is confidential and not to be disclosed," Robbins told The Times through an employee.

Obama's campaign did not respond to a Times inquiry into the event, and May spending records have not yet been filed with the Federal Election Commission.

Gino Baldin, manager of Schererville's Villa Cesare, said the banquet hall has sent the Clinton campaign a bill for a May 1 Bill Clinton visit. Baldin could not recall the amount due, but renting a single room is $500 and $1,000 for the whole hall.

A Clinton spokesman said in an e-mail that the campaign pays vendors approximately a month after getting invoices and expects to pay its Northwest Indiana bills in the next three weeks.

The venue, equipment and other amenities were donated in some of the visits, including Hillary Clinton's April union-hosted stops to Portage's Duneland Falls Banquet Center and McBride Hall in Gary.

When the New York senator made her first local stop to Hammond in March, the 5,000-seat Civic Center came rent-free.
