But Michael Hancock's troops have taken things one step further. They're offering to pick up your ballot and deliver it for you.
Yep, phone 303-307-9891 and you, too, can save a trip to a polling location. Hancock spokesman Amber Miller says there's a team of volunteers on duty today specifically charged with this chore.
How did the idea come about?
"We have a ballot bus, with big billboards on the sides, and Michael's been on it a lot of the time during the campaign, going around to different neighborhoods," Miller notes. "And people hand him ballots when they see him. They're like, 'Oh, mine's in my car,' or 'Mine's at my house. Do you want us to go and grab it?' And we've been helping out as much as we can -- helping people get to voter stations, or if they can't, picking up their ballots and delivering them."
The campaign hasn't kept track of the total ballots delivered to date, but Miller thinks "hundreds" is a good guess -- and in a ten candidate race where only the top two can be included in a widely anticipated runoff, each ballot is key.
"A lot of people have the false impression that you can get your ballot postmarked today and it will be counted," Miller maintains. "But it won't. So we're out there making sure people understand how the process works. We're going door to door today, asking people, 'Is your ballot on the coffee table? Can we help you deliver it?' And if not, just reminding them that they can't mail it. They have to take it to a voting station" -- to find locations, click here.
Of course, such a service might be exploited by opponents. Has the Hancock camp received calls from other candidates' supporters, forcing them to spend valuable resources to deliver ballots that will go toward someone else?
"Not that we've seen," Miller says, "and that would be some impressive effort on election day. The way it's gone so far has been when Michael's at a coffee shop or a grocery store and he's talking to people, they'll say, 'Oh, I have it,' or 'I'll be at my house at five o'clock.' It's not typically something where people have been calling in and saying, 'We have eighteen ballots in eighteen different places -- can you pick them all up?'"
Then again, it's still early...
