During the presidential elections of 2008, Pierson claimed that she had voted for president Barack Obama but later found herself disagreeing with the policies he implemented. That would be the start of her changing political beliefs. In 2009, she became an active Tea Party member. She had such a strong passion for the political party, she founded a Tea Party group in Garland, Texas. In the 2012 Texas Senate, Pierson publicly supported candidate Ted Cruz. She was even on stage with Cruz on the night of the election.

Pierson’s endorsement of Cruz would continue through the 2014 Texas Congressional elections. Cruz reciprocated the support by labeling her as a fearless principled conservative. After Cruz lost, Pierson moved on and became a spokesperson for the Tea Party leadership fund.

Although the details of her salary are not available publicly, there are rumors that she was paid $30,000 to become the public face for the Tea Party Member campaign, which lasted for a duration of 6 months. There are also whispers by the political media that she gets paid amounts that are undisclosed. She made enough money with her jobs before her political activism but she must be receiving funds from unknown sources to allow her the time to voice her political views on so many platforms.Pierson
