Cowboybyte.com has the story:
Donald Trump supporters have met an official ballot deadline in Texas, paving the way for the business mogul to become a third-party candidate there, a source close to Trump tells The Blaze. Trump himself acknowledged the filing in a statement.
Here is the original The Blaze story to which the Cowboybyte story refers.

Texas won’t let new party petitions start to circulate until April 2012. So no money is being spent on the “Make America Great Party” in Texas or any other state at this time, unless one counts the price of a postage stamp to file the state form with the Texas Secretary of State.
The last paragraph of cowboybytes says these folks are setting up this new party so Trump can “run in the primary” if he wants. I assume that’s run in the general if he wants?
I’d be interested to know if Trump is funding the potential petitioning to get “Make America Great Again Party” on the ballot?
And I’d love to know if these people are professional political operatives?
I did a couple searches and can’t find any web presence for this party.
