The right wing of the Republican Party is fighting for a victory in New York's 23rd Congressional district Tuesday, hoping that a conservative candidate can secure a seat and help ignite a purge of moderates from the GOP. "Moderates by definition have no principles," Rush Limbaugh said during his radio show Monday. Democrats have also seized on the conservative excitement for a win, sending Vice President Joe Biden to the area Monday to stump for his party. "Sarah Palin thinks the answer to energy is 'Drill, baby, drill,'" Biden said. "It's a lot more complicated, Sarah." A recent poll showed the conservative candidate Doug Hoffman leading his Democratic opponent Bill Owens by 5 points, with 18 percent of voters undecided.
