The MAGAts had the idea to write in "Trump," but their plan has a major flaw.

Reading is fundamental. :)

The Colorado ruling is not likely to change anything in a practical manner. My guess now is that Trump will still win the GOP primary even if his name is not on the ballot, as all his followers write him in as a candidate...

Guess again, CW:

Accordingly, we conclude that because President Trump is disqualified from holding the office of President under Section Three, it would be a wrongful act under the Election Code for the Secretary to list President Trump as a candidate on the presidential primary ballot. Therefore, the Secretary may not list President Trump’s name on the 2024 presidential primary ballot, nor may she count any write-in votes cast for him. See Section 1-7-114(2), C.R.S. (2023) (“A vote for a write-in candidate shall not be counted unless that candidate is qualified to hold the office for which the elector’s vote was cast.”).

The ruling also bars the Colorado Secretary of State from counting any write-in votes for Mein Drumpf.

But their plan has a major flaw: the court's ruling also bars the Colorado secretary of state from counting any write-in votes for Trump.
