Democrats now hold the governor’s office and both legislative chambers in Minnesota, Michigan, Nevada, Pennsylvania and Wisconsin. Arizona could follow if outstanding House and Senate races break their way, after Katie Hobbs won another term as governor.

Virginia last year, after similar one-party control, adopted bans on certain rifles, a purchase age of 21, storage rules, open-carry limits and extra no-carry areas. Those states may also face permit-to-buy rules for semi-automatic long guns, limits on suppressors and short-barreled firearms, more restricted locations, extra training for concealed-carry licenses, and a possible end to permitless carry in Arizona.
