Democrats looking to keep Arizona blue are counting on abortion rights to carry them this fall, a bet that might not pay the same dividends it did two years ago.

Across the state, abortion rights activists are gathering signatures to place a measure on the ballot putting abortion protections in the state’s constitution. In doing so, organizers hope this will galvanize Arizonans to vote blue at the polls in a state where about one-third of registered voters are independents.
