This is indeed tragic news. Representative Wexton has run spirited re-election campaigns against the GOP since 2018 and both sides of the aisle wish her the very best in the battle with this horrific disease. Looking forward, her absence in 2024 will ultimately translate to a competitive race, with politicians from the Democratic and Republican parties looking to win the opportunity to serve those in Wexton's district with the same commitment and conviction the representative has shown throughout her long career.
Although the GOP and Democrats can unite in recognizing the service and dignity of individuals like Wexton, there is very little else they can agree on. The dramatic rise is partisan animosity in the US in recent years has undermined American democracy, stifling dialogue and legislative progress. Wexton's service to those she represented should be recognized, though it should also be highlighted that her career is not indicative of the current festering gridlock that characterizes US politics.
There's a 50% chance that at least 95% of the US 2024 presidential popular vote will be received by the Democratic and Republican parties (combined), according to the Metaculus prediction community.
