Hardball host Chris Matthews is still serious about running against Pennsylvania Sen. Arlen Specter in 2010. While allies once thought Matthews was just floating a Senate bid to help in his contract talks with MSNBC, they now tell us that he's eager to reach out to important Pennsylvania voting groups and leaders and has even won the backing of his wife. One big concern: his nasty hit on Sen. Hillary Clinton as a "she-devil," for which he was slammed as sexist. "He is concerned he ruined it with the women vote," says an associate. So he's drawn up a list of feminists to contact. Even so, we're told, there's one woman who won't go to bat for the Democrat: Clinton.
