Who is endorsing Kelly Brough and Mike Johnston for Denver mayor

Endorsements are racking up in the Denver mayor's race as the June 6 runoff nears — and they're proving almost as interesting as the contest itself.

Why it matters: An endorsement from key groups can unlock significant campaign funding and robust turn-out-the-vote efforts.

• Who's backing who can also sway some voters who are still on the fence.
