(CNN) - If "extreme" was the buzzword in the first Pennsylvania Senate debate, "economy" was the hot topic in the second debate between Republican candidate Pat Toomey and Democratic Rep. Joe Sestak on Friday.
Both candidates continued themes they have used throughout their campaigns - painting each other as "extreme" while attempting to showcase themselves as moderates.
Sestak, a former U.S. Navy admiral and two-term congressman, touted his military record and focused on attacking Toomey as someone who would cater to Wall Street.
"He supports any program that helps corporations, that help Wall Street," Sestak said.
Toomey, a former congressman, pushed his record as a business owner and job creator, and criticized Sestak for being an "extreme" liberal who voted for the bailout of Wall Street banks.
"We badly need people in Washington who have business experience," Toomey said. "Joe has no experience in business and does not understand the consequences of the really bad policies he's been proposing."
Toomey went on to advocate for lower tax rates and emphasized the need to lower capital gains taxes "across the board."
Sestak defended his position on middle-class tax cuts and said he was for a "zero capital gains tax" for investors in small businesses.
During the energetic hour-long debate in Pittsburgh, Pennsylvania, the candidates dug in on tax policies, job creation and spending, sniped over inconsistencies in each other's voting records, and often ignored the moderator's time-keeping requests.
Recent polls show the race to claim Sen. Arlen Specter's open seat is deadlocked among likely Pennsylvania voters. The party-switching senator was defeated in the Democratic primary by Sestak.
