Ivan Moreno, who has been all over this story, for AP: “Colorado Democrats are planning sweeping changes to how elections are run in the state, to the dismay of Republican leaders who say they’ve been excluded from crafting a bill that that would allow same-day voter registration and require mailed ballots to every eligible voter. A bill of more than 100 pages is expected to be introduced this week, likely sparking a big partisan fight over whether the changes benefit one party over the other.”
