Topeka ? Kansas Sen. Sam Brownback says he’ll vote against a second term for Ben Bernanke as Federal Reserve chairman.

Brownback said Wednesday he believes the Fed needs a different perspective because its Board of Governors is too dominated by Washington and New York interests.

Aides to Brownback’s fellow Kansas Republican, Sen. Pat Roberts, didn’t immediately respond to messages and e-mails Wednesday about how Roberts plans to vote.

The Senate is expected to take a vote Thursday that will determine if Bernanke’s nomination will overcome procedural obstacles. Supporters need 60 votes in the 100-member Senate.

Brownback said he wants a Fed chairman from outside the establishment, mentioning Thomas Hoenig, president of the Federal Reserve Bank of Kansas City.
