AUSTIN, Texas – Hillary Rodham Clinton‘s free-spending campaign blew a whopping $95,000 at a low-end supermarket-deli chain last month in Iowa – a telling sign of why she can no longer cut the mustard financially against Barack Obama in critical states.

Clinton’s latest campaign filings reveal how a sprawling, top-heavy campaign organization splurged on posh hotels and pricey consultants but still struggles to define its message against Obama, a charismatic opponent whom Clinton’s camp now calls the front-runner.

The $95,000 charge came at the Hy-Vee store in West Des Moines, a grocery and deli chain that is a fixture in the state, on Jan. 1, just two days before Obama stunned Clinton by beating her in the Iowa caucuses.

The campaign didn’t confirm what the charges were for, but it bragged just a few days before the new year about a plan to provide deli sandwich platters at caucus sites across the state in order to get Clinton’s supporters to come early.

At the time, the idea seemed like evidence of Clinton’s massive turnout operation, but in hindsight it indicates Clinton’s support was soft compared to Obama’s hungry army of first-time voters.

The heavy spending helps explain why Clinton’s camp ended the year $7.6 million in debt, not including her $5 million loan to her campaign.

The campaign team has plowed through $116 million so far.
