Voting by mail

The Supreme Court justices said in an opinion Monday night that the government is “unlikely to succeed on the merits of its challenge.”

Colorado Attorney General Phil Weiser has joined a lawsuit opposing new rules on mail-in balloting.

Election officials say the state's mail voting system remains one of the most widely used and trusted in the country, even as questions about election security persist.

President Trump signed an executive order that sets out a list of new mandates for states to follow for mail-in ballots, or face the loss of federal funds.

If President Donald Trump gets his way, Colorado’s all-mail voting system will be a thing of the past.
