And, pray tell, what kind of a future does this party have that believes in nothing and everything? Or does everyone live just for "the party" whatever it is?
The goal of political party in our 2 party system is to win. That is the cold, hard truth. It will always be more about winning than advancing any particular cause. There will ALWAYS be an establishment steering the party, and it's goal will ALWAYS be to win at almost all costs. No matter which way the culture moves - left or right, political party's will tend to follow. They will tend to hug the center to get 50% + 1 voters and win. Far more things influence society than just politicians. Unfortunately, some of the biggest influences on our culture right now are coming from the left - entertainment, education, etc.
Our mission within the political party that at least pretends to be conservative, the GOP, is push it to the right and try to nominate the most conservative candidate that can actually win - hopefully one with an actual vision that includes moving the country politically in the right direction. Unfortunately, there are many people under the umbrella of the same party that do not want to push the party to the right. We have to compete with them. Unified in the primaries, conservatives do have an advantage over "moderates" and should win much/most of the time. Unfortunately, we are rarely unified - and weren't yet again this year.
