BILL-ARY: And you will know them by their trail of debt. IMAGE: chrisryanphoto.com

As Sen. Hillary Clinton’s bid for the Democratic presidential nomination flames out, her campaign leaves behind more than $40,000 in unpaid rental costs and overtime fees at Oregon public schools where she and ex-President Bill Clinton spoke.

With nearly $20 million in declared debt as of April 30, it’s little surprise the Clinton campaign is behind on its Oregon bills. Most school officials we spoke with expressed confidence they’ll be repaid, even as the Clinton campaign tottered into the final primaries on Tuesday.

Clinton has already coughed up more than $150,000 to pay Portland-based West Coast Event Productions for organizing most of the campaign’s Oregon events. But at a time when education is a staple issue, her failure to pay public schools as promptly surprised some.

“It really, really disappoints me,” says Diane Zaske, building coordinator for the Oregon City School District, which has invoiced the Clinton campaign twice for the $1,440 it’s owed after Bill Clinton spoke April 26 at Oregon City High School.

(We also checked with many Oregon venues where Sen. Barack Obama spoke and found that his campaign—which declared $46.6 million in hand as of April 30—had paid its bills promptly.)

The list here, from five trips to Oregon by the Clintons, does not include two schools the Clinton campaign paid. Nor does it include several schools that have not yet billed the campaign or did so only recently—including McMinnville School District ($1,700), North Bend School District ($600), Redmond School District ($450) and Corvallis School District ($150). Besides schools, we included the Jackson County Fairgrounds, another publicly supported agency owed $6,500.

The Clinton campaign in this already tough week didn’t return calls seeking comment.
