Ron Brownstein: “The last five times a president went into a midterm election with unified control of government, voters have revoked it. That list includes Joe Biden in 2022, Trump in 2018, Barack Obama in 2010, George W. Bush in 2006, and Bill Clinton in 1994. This streak seems virtually certain to continue next month with Republicans on track to lose the House and maybe the Senate.”“That will extend a dismal record, raising to six the number of consecutive times a president has gone into a midterm with unified control and lost it.”
