The special election in Arizona’s 8th District will set the stage for a hotly contested Senate race and a handful of competitive House races in the Grand Canyon State. And both parties are watching for indications of what’s to come in November.
More than 150,000 people have already voted in the contest to replace Republican Rep. Trent Franks, who resigned in December amid allegations of sexual misconduct. Democrats are hopeful they can make the race close even though President Donald Trump carried the suburban Phoenix-based district by 21 points in 2016. And Republicans know analysts will be looking at the outcome for signs of a potential blue wave.
