No one really likes the two party system, but both sides will, in the end, vote for their party's candidate. Why? So that the other party's candidate doesn't get in.
Let's face it, we like to blame the system for the lack of choice, but when it comes time to choose, our selection ends up being from one of the two major parties. In the end, we make up the system, we are the system. As Pogo said: "We have met the enemy, and he is us."
It's going to take some work to change that. Work by us, the system. If you don't like what you see, then get active in the GOP. Join! Go to the local meetings and speak your mind. There are things that you can do. If you are doing things, bravo! If not, why not? As Ronald Reagan said: "If not us, then who? If not now, when?". And let me add this: "If not us, then it will be the RINO."
Having said that, the more I listen to what Barr has to say, the more I like him.
