These weren't Mike Badnarik backers
Who
was?
I think the original Tea Partiers were largely Ron Paul backers.
Here's how Paul himself described things in 2013:
The Tea Party was actually started during the Ron Paul presidential campaign in 2007 when there was a spontaneous moneybomb that was done on the anniversary of the original tea party. And it was strictly related to the issues and ideas I have just finished talking about. What happened after that was that a lot of people came onboard including Republicans who watered down some of the beliefs, and certainly changed the opinion of some on foreign policy so that the original Tea Party movement was taken over by the Republican Party, which I think was part of the problem.
Paul's recollection is consistent with the reporting back in 2007.
This may have been the beginning of the Tea Party:
Hoping to detonate what they call a "money bomb," [Ron Paul's] supporters started fundraising at midnight Saturday and have already raised $2 million as of about 10:30 a.m. today.... [T]hey're seizing on the 234th aniversary of the Boston Tea Party and converging on this snowy city to rally.
That's how Dave Weigel
recalled things in 2010 as well:
The first modern Tea Party events occurred in December 2007, long before Barack Obama took office, and they were organized by supporters of Rep. Ron Paul, R-Texas, to raise money for his long-shot presidential bid.
