Democratic Congressman Ruben Gallego leads Republican Kari Lake by a significant margin in the Arizona Senate race, with a new Fox News poll showing Gallego at 56% compared to Lake's 41%. This 15-point lead is the largest gap reported in recent surveys, which also indicate that down-ballot Republicans are struggling in key races across the country. Despite the unfavorable polling, Lake claims that her internal data shows her in the lead, criticizing the public polls as 'absurd' and 'partisan.' Gallego has garnered support from the Arizona Police Association and has solidified his backing among Democrats and independents, while Lake faces challenges in appealing to swing voters. The candidates are set to debate on October 9, coinciding with the start of early voting in Maricopa County. Lake's past controversies and her alignment with Trump may hinder her ability to attract undecided voters.
