Trader consensus favors Democrats at 73% implied probability to win Arizona's 1st Congressional District open seat race, reflecting State Rep. Amish Shah's dominant position in the Democratic primary—leading 3-to-1 in late February polling—and a fragmented Republican primary where State Rep. Joseph Chaplik holds just 24% support amid 54% undecideds per an April survey of likely GOP primary voters. Recent local polling highlighted April 28 noted swing voters shifting toward Democrats in this former toss-up district (previously rated even by Cook Political Report), amid Democratic voter registration gains in key Maricopa County areas. July 21 primaries loom as the next catalyst, with general election November 3.
