MADISON (WKOW) -- A government watchdog group says outside groups have spent more than $20 million in Wisconsin's gubernatorial recall.
Republican Gov. Scott Walker faces Democratic Milwaukee Mayor Tom Barrett in Tuesday's recall election.
The Wisconsin Democracy Campaign has been tracking recall spending since the recall drive began in November. The group says outside special interest groups have spent $21.5 million on the governor's race.
The top spender is the Right Direction Wisconsin political action committee operated by the Republican Governors Association with $8.7 million.
The second biggest spender is the Greater Wisconsin Political Independent Expenditure Fund, a corporation created by the liberal attack group Greater Wisconsin Committee. The fund has spent $4.8 million.
