"By naming Sen. Bob Menendez (N.J.) vice chairman of the Democratic Senatorial Campaign Committee, current Chairman Charles Schumer (N.Y.) may be quietly laying the groundwork for his prospective successor," according to Roll Call.
"Like Schumer, Menendez is known as one of the Democrats' most ambitious Senators as well as a prolific fundraiser and aggressive campaigner."
"Democratic sources say Menendez's recent appointment -- a decision made by Schumer and Majority Leader Harry Reid (D-Nev.) -- makes clear the New Jersey freshman and prominent Hispanic is an early favorite to take over the DSCC in 2010."
