Here’s what happens when a tea party darling becomes the movement’s enemy

The first "Tea Parties" weren't a political association. They were events, spontaneous gatherings of citizens concerned with the direction of the nation. "Taxed Enough Already" was a cute play on the word "TEA" which followed the first tea parties. Professional politicians quaked at the sight of these events because they were a true grass roots movement. Nancy Pelosi infamously attacked them as "Astro-turf" and operatives attempted to establish a narrative that these gatherings weren't spontaneous, but rather paid for by nefarious persons such as the evil Koch Brothers. Anything to discredit them. Sadly, like most people who vent their spleen in public outcries, the attendees picked up their trash and went home hoping they had effected real "change". They hadn't. Real change requires a steady application of pressure over time, long periods of time. Look at how long the progressives took to establish their narrative and move the nation to the left - more than a century. Efforts like that need organization and some have attempted to capitalize on those first spontaneous gatherings. "Tea Party" organizations have sprung up. I've attended a few. Sadly, they're poorly organized and currently dominated by the loudest, not necessarily the wisest voices. Thus, they are not the official voice of conservatives. Conservatives simply haven't yet discovered that they need a voice. I hope they do before it's too late...

The problem with most politicians is they forget and abandon the philosophies for which they where elected. Many in Washington are beholding to special interest groups and fall under the pressures of the Washington Cartel. I would suppose Bernie Sanders feels extremely ostracized by the DNC. So in reality it is not surprising that anyone would fall out of favor when rocking the boat.

Thankfully the Tea Party is not a monolithic movement SSG Michael Hartsfield
I have been a first principal voter for decades and embrace some of the core Tea Party concepts.
I receive emails from national and local groups which range from conservative republican to libertarian in their focus.
As far as Renee Ellmers is concerned, there are always some people who will dissatisfied with how their elected official performs once in office.
