A rumor is moving around Denver City Hall that District Attorney Mitch Morrissey is being encouraged to run for mayor. It is unconfirmed.
Some Denver police, in particular, have expressed unhappiness with department changes, and the Mayor is dealing with angry local park advocates. Those two departments are large with powerful constituencies. Mayor Hancock is also struggling to contain the rivalries of regional neighbors in Adams and Arapahoe counties.
The next election is May 2015, a long ways off. Incumbent mayors tend to be re-elected, even those with very controversial first terms, like Federico Pena and Wellington Webb.
But some constituents may be sending a message.
