As pointed out by @VickyStL on Twitter, it turns out that Loesch's new astroturf venture was registered on December 1:
Why is this important? Because many on the Team Wagner side of the split acted offended by the 24th State post criticizing Jim Hoft's attack on Ed Martin. However, that post wasn't until December 3rd. In other words, it looks like Loesch and/or Scott Boston was planning this new group before anyone from the St. Louis Tea Party had ever publicly criticized Hoft.
