(CNN) - "In a September session, it's hard to separate anything you do from politics."
Independent Connecticut Sen. Joe Lieberman's explanation for the Senate's decision to wait to vote on extending the Bush tax cuts until after the American people vote in November is indicative of the political gridlock in Washington and the political battles being waged around the country.
"We didn't get much of anything done," Lieberman conceded Sunday to CNN Chief Political Correspondent Candy Crowley on State of the Union.
Lieberman predicted that when lawmakers return to the nation's capital after the midterm elections, they will permanently extend tax cuts to families making less than $250,000 a year and extend the Bush tax cuts for Americans making more than that for "at least a year or two."
Lieberman said it's easy to make wealthy people a boogeyman but said they're the ones who spur economic growth.
If Congress fails to act, Lieberman said, "everybody's taxes go up in January."
Lieberman is one of two independent senators; he will be up for re-election in 2012.
