“they constrated on the 6 states that are in the middle!”
Republicans won the majority of House of Representatives seats in Georgia, Pennsylvania, Michigan, and Wisconsin. They won both houses of the legislatures in Georgia, Pennsylvania, and Wisconsin, and the Michigan House of Representatives. (The Michigan Senate was not up for re-election this year.) Republicans also won two of three statewide elected offices in Pennsylvania that were up. Republicans also won both houses of the Arizona legislature, although Democrats did better on the federal level, winning 5 of 9 US House of Representatives seats and flipping the US Senate seat as Martha McSally lost for the second time in two years.
I guess if you think that all of those states had void elections, we should kick all the Republicans who won out of office. It would give the Democrats a nice comfortable majority in the US House of Representatives.
