President Trump’s two most prominent primary challengers will be on the presidential ballot in Texas next March.

On Monday, former Massachusetts Gov. Bill Weld and former Illinois U.S. Rep. Joe Walsh officially filed for the primary ballot in Texas. Weld and Walsh are considered by many to be Trump’s most prominent primary challengers, as former South Carolina Gov. Mark Sanford withdrew from the race last month. California businessman Rocky De La Fuente, who is running a national campaign to primary Trump, will also appear on the Texas ballot.

In addition, Bob Ely, Zoltan Istvan, and Matthew Matern will appear on the primary ballot.

On the Democratic side, all major Democrats have filed to take part in the primary.

The primary will be held on March 3, 2020.
