Lieberman Files Forms for Independent Run

U.S. Sen. Joe Lieberman filed papers Monday that will allow him to petition his way onto the November ballot if he loses the primary election, his campaign said.

The three-term Democratic senator faces a tough Aug. 8 primary challenge from businessman Ned Lamont. Lieberman, whom fellow Democrats have criticized for his support of the Iraq war and a perceived closeness with President Bush, is popular among many unaffiliated and Republican voters in Connecticut.
