Schumer, Durbin quietly jockeying to replace Reid as leader

WASHINGTON — Senator Charles E. Schumer shipped $500,000 to Nevada in recent weeks to help Harry Reid, the Senate majority leader and Mr. Schumer’s political patron and close friend, as he fights for his political life.

At the same time Mr. Schumer, a New York Democrat, made out a smaller check, for $20,000, to the Democratic Party in Vermont, where the gift earned him the good will of Senator Patrick J. Leahy, even though Mr. Leahy is not believed to be in any serious re-election jeopardy.

“Senator Leahy takes no election for granted and is grateful for Senator Schumer’s support,” said Carolyn Dwyer, campaign manager for Mr. Leahy.

The two donations underscore the excruciatingly delicate position Mr. Schumer finds himself in these days. He is doing everything he can to help his friend Mr. Reid fend off a challenge from the Tea Party candidate Sharron Angle and prevent the embarrassing ouster of the party leader.

Yet given his own deep political ambitions and drive, Mr. Schumer is also very carefully laying the groundwork to move on a moment’s notice to try to secure the top Democratic job if Mr. Reid is defeated on Tuesday.

The situation for Mr. Schumer is further complicated by the fact that his partner in the Senate leadership and Capitol Hill housemate, Senator Richard J. Durbin of Illinois, is also positioning himself in the underground campaign to replace Mr. Reid, though both men have made it clear they would greatly prefer that Mr. Reid return. The senators and their aides declined to comment for this article.
