Why did tea partiers take a previously noble idea and corrupt it by taking the same name?

The original Tea Partiers were protesting taxation without representation. I'm going to take a leap here and ume that most Tea Party protesters are American citizens and most of them aren't felons.. as such, if they haven't been "represented" they haven't been voting, leaving them exactly 1 person to blame.. I see no parallels behind the greedy "I want all of my money and don't want to help America" people and the original protesters, who were being taxed without representation
