What I see are some people who abandon ship when their pet cause isn't handled the way they wish. That is their privilege, but they are one-issue voters and because of that lose clout with the party.
I look at the sum total of what is being done. Perhaps economic policy isn't as conservative as I would like, but on the other hand military policy is better than I expected. In balance, I have to sick with the guy who is honest about his opinions, even when I don't share all of them, as opposed to someone who is chasing the polls in an obvious grasp for power.
There are two schools of thoughts on this, but I think I have made my position obvious.
