Editors note: This is a daily summary of news about the U.S. Senate race between U.S. Sen. John Sununu (R-Waterville Valley) and former Gov. Jeanne Shaheen (D-Madbury).

Judy Reardon, a senior advisor to the Shaheen campaign, e-mailed supporters telling them to sign a petition against the Enron loophole.

"Lobbyists for Enron crafted the so-called ‘Enron loophole,' which allows large energy traders, such as billion-dollar hedge funds, to trade on an electronic exchange with little government oversight. This loophole allows the kind of rampant, unregulated speculation that is responsible for $40-70 of the inflated price of a barrel of oil," the e-mail states. "Tell John Sununu to stop putting the needs of billion dollar hedge funds ahead of the needs of middle class families. Tell John Sununu to help bring down the cost of gasoline and close the Enron loophole."

The New Hampshire Democratic Party filed a complaint with the FEC against a group that is running radio ads criticizing Shaheen's economic record.

Josh Rogers of NHPR analyzed the U.S. Senate race for National Public Radio. The story features quotes from New Hampshire Republican Party Chairman Fergus Cullen, President George W. Bush, Shaheen and Sununu.
