Colorado Secretary of State Scott Gessler says Colorado now has more registered voters than ever.
Gessler said Wednesday that preliminary results show there are now about 3.6 million registered voters in the state. That includes more than 79,000 people who registered from Sept. 1 through the deadline Tuesday.
The total of 3.6 million registered voters is up from 3.2 million in 2008 and almost 3.3 million in 2010.
The final tally for 2012 is expected to rise, as last-minute registrations continue to be processed.
Gessler's office had launched a multimedia campaign in September to encourage people to register.
Gessler also led an effort this year that asked 3,903 people on voter rolls to verify their citizenship. That resulted in finding that 141 non-citizens were illegally registered to vote.
