The problem is the majority of the public is not particularly conservative. This is not the 1950's where there was a population of patriotic Americans that could be prodded to do the right thing when the chips were down. This is 2013 America where Hispanics of Mexican heritage are the fastest growing voter demographic and they support leftist policies (there is a reason the socialist PRI was in power for 75 years in Mexico). We are quickly becoming a center left country that wants to go down the road of European secular socialism.
We're just not going to get really pure conservatives in many states, it just isn't going to happen. In some places you can pull that off, but in others we are going to have to settle for less than perfect candidates that can win. As the article points out, supporting ding bats like O'Donnell was a mistake. The Tea Party needs to support the most conservative candidate that CAN win a general election.
The Tea Party is demonuzed by the Left because they are patriots who will stand, fight against, and expose the lies and deception they disseminate. The Tea Party is nowhere near close to dead. In fact they are gathering even larger numbers and solidifying their base and learning to change their tactics by taking the time to study the enemy to see what makes him tick and the strategies they employ. One thing has become clear - Intellectualism is one of the Achilles Heels of the Left. It is not the advantage they believe it to be. In fact it can be used as a weapon against them.
