Newly-minted Sen. Mark Udall (D-Col.), has scheduled a press call this afternoon to announce his plans to introduce legislation to end the abusive practices of credit card issuers.

Carolyn Maloney (D-N.Y.), and he has vowed since the election to introduce the same bill in the Senate. But his push in the Senate is interesting for several reasons.
