Republican Sen. Ron Johnson repeatedly faced laughter and boos from the audience gathered at Marquette University on Thursday for the final debate between the two-term GOP incumbent and Democratic challenger Mandela Barnes in Wisconsin's key U.S. Senate race.
With less than a month to go before the November midterms, Barnes — Wisconsin's lieutenant governor — took Johnson to task over his opposition to abortion rights, support for cutting Social Security and Medicare, and 2017 vote in favor of former President Donald Trump's deeply unpopular and regressive tax cut for the rich and large corporations.
