New York ? After weeks of pressure from her own party to drop out, Republican Jeanine Pirro abandoned her struggling campaign to unseat Sen. Hillary Rodham Clinton and announced Wednesday that she will run for New York attorney general instead.

“I have decided that my law enforcement background better qualifies me for a race for New York State attorney general than a race for the United States Senate,” Pirro, the Westchester County district attorney, said in Albany.

With her campaign against Clinton in trouble, Pirro had been under strong pressure from top state GOP leaders to make the switch.

A Democratic strategist said the development could only boost the former first lady’s already solid standing as a potential 2008 presidential contender.

The move leaves Republicans with two active candidates for the Senate nomination: former Yonkers Mayor John Spencer, who is not well known statewide, and an even less well known tax attorney from the Catskills region, William Brenner.
