The last time a Denver mayor lost a re-election bid at the ballot box was in 1983. So it’s not an exaggeration to say that in two months when Denver voters cast ballots in the first open mayoral race since 2011 when Mayor Michael Hancock was first elected, they could dictate the course of the city for more than a decade. Whether that opportunity — or the stakes — will drive turnout up over the 40% of voters who cast ballots in the city’s May 2019 election when the term-limited Hancock was last elected remains to be seen.
