In an interview with Esquire, U.S. Sen. Scott Brown, R-Ma., gave a terse answer when asked about his working relationship with Senate Minority Leader Mitch McConnell, R-Ky., who spearheads the Republican agenda.In a GOP where northeastern moderates are abandoning the party in protest, Brown is running as a "good guy" while seeking re-election in the closely watched race with Democrat Elizabeth Warren for Ted Kennedy's old seat. The moderate Republican lawmaker gained fame as a Tea Party candidate two years ago, but he's been decidedly moderate and recently praised his opponent in a new radio ad.When asked how his moderate streak compares with McConnell's leadership, Brown got snippy.From Esquire:
