Washington voters weigh federal races, carbon tax, gun law

In this Thursday, Oct. 4, 2018, photo, staff members for the Yes on I-1639 campaign, a gun safety initiative, prepare campaign materials at their headquarters in Seattle. Voters will decide the fate of I-1639, which would toughen background checks for people buying semi-automatic rifles, increase the age limit to 21 for buyers of those guns and require secured firearm storage in the Nov. 6, election.
