Section 3 of the 14th amendment of the United States Constitution is as listed

No person shall be a Senator or Representative in Congress, or elector of President and Vice President, or hold any office, civil or military, under the United States, or under any state, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any state legislature, or as an executive or judicial officer of any state, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof

In simpler terms meaning anyone who has previously taken an oath as a member of our government, and has engaged in an insurrection or rebellion against the USA is not eligible to be re-elected into a seat in our government. 6 voters in Colorado filed a lawsuit in an attempt to keep Donald Trump off of the primary election ballots in Colorado, citing the 14th amendment and the events of January 6th, 2021 as his moment of aid or engagement in insurrection.

Surprisingly, the 6 people who are filing this lawsuit are comprised of Republicans and Unaffiliated voters, wanting to keep Trump off the primary ballot so that he does not siphon off votes from candidates of their choice.

The article says that there have been other events like this in other states calling for Trump to be removed from the primary ballots. It says that this is completely separate from the legal troubles Trump is currently facing, and that whichever way that case ends will not affect this. The supreme court of Colorado will need to decide what counts as aiding or engaging in an insurrection.

I think this article does a great job at explaining what happened and many of the gritty details behind why they can do this, and why it may or may not work. I think in general that it is a very interesting event, and could change things in the future. If they rule in favor of Trump rather than the voters, many are sure he would be the next Republican Candidate, so this case (and the others like it across the nation) will have a huge impact on our country.
