Like many first-time voters in Colorado, Melissa Blanchard registered for the election this year and received her ballot.

But instead of coming to a personal mailbox, it came to Samaritan House Homeless Shelter, where she has been living.

“I registered to vote, because this election is very important,” Blanchard, 40, said on Monday. She cast her ballot for Donald Trump.

The Colorado Secretary of State’s office joined an effort aimed at encouraging the homeless to vote this year, registering them at shelters and elsewhere.

About 600 people who either live at St. Francis Center, or have their mail sent there, have received ballots so far, said Tom Luehrs, the day shelter’s executive director. “One of our staff said they were impressed by how many people have been picking them up and filling them out,” he said.

But Luehrs, and others involved with the homeless population, said they didn’t know how many homeless have registered as a result of the state’s efforts.

“We have about 1,500 people registered,” Luehrs said.

About 100 people registered at the Denver Rescue Mission on Lawrence Street, said Alexxa Gagner, the Mission’s spokeswoman. Another 20 men have sent in their ballots from The Crossing, where participants in a Rescue Mission transitional program are housed.

“We have a lot of people who get mail at different locations, so any ballots that come in and aren’t claimed, we send back to the Post Office,” Gagner said.
