Here's the joke: 

“Better Colorado Now backs candidates who are not afraid to step up and solve big problems for our state,” said Gregg Engles, a member of the host committee, in a statement.

The punchline? The "big problems for our state" include how to evade campaign donation limits to flout the rules that restrict big money influence in our elections. 

And the "candidates"? Just one guy who is actually the state treasurer. Who would know better how to cheat?
