State officials say more than 217,000 people have registered to vote in Colorado this year, including nearly 113,000 since the end of July.
Monday was the deadline for registering to vote in the November 4 election.
Richard Coolidge, a spokesman for Secretary of State Mike Coffman, says about 1.1 million Coloradans have requested mail-in ballots, or nearly a third of the total.
Coolidge says county clerks have canceled the registrations of more than 58,000 voters since January, about 2 percent of tote total.
Nearly 31,000 had moved to another county or state. Nearly 14,000 were duplicate registrations and nearly 8,000 had died.
More than 2,200 were canceled because they were felons.
