DENVER – Democrats say former President Bill Clinton has bowed out of a scheduled appearance to lend a hand to a pair of embattled Colorado candidates following the birth of his granddaughter.

Clinton was to speak at a fundraiser today for Sen. Mark Udall. Gov. John Hickenlooper was also scheduled to be at the event. Both Democrats are locked in tight re-election battles with their Republican challengers.

Clinton’s daughter, Chelsea, gave birth Friday to her first child, a daughter named Charlotte.

Clinton has been traveling the country to help Democrats in 2014.

President Obama did come to Denver to raise money for Udall in July but the senator stayed in Washington, D.C., saying he couldn’t miss votes in the capitol.
