Arizona remains a state where the Republican and Democratic parties are very close. As Senator Krysten Sinema a Democrat, supported the Republican filibuster that required 60 votes for major legislation and thwarted some of president Biden's legislation to help workers and families in the US. Having alienated some Democrats she is now running for the Senate as an Independent. Her likely opponent from the Republican party is Kari Lake. Arizona is split three ways evenly for Republicans, Independents and Democrats. The question for Sinema says a Republican strategist is whether there are enough independents and soft Republicans who will vote for Sinema. Rep. Ruben Gallego is running for Democrats, Kari Lake for Republicans. Another question is whether Kari Lake's association with Mr. Trump could hurt Republicans in Arizona. Synema faces a difficult three way race as Democrats see her flagging support on key initiatives of the president as a serious problem.
