If you grow the party...One of the major parties will run the government. It sounds like you don't like the Democrats. If that's true, then do what you can to defeat them and you will have accomplished something for yourself and for the rest of us that feel the same way.
Right now too many Republicans are acting like Democrats including President Bush. I'll keep working to turn him around but if he keeps going the way he's going I'll vote third party.
I can't see enabling someone who is narrowing the difference between the parties.
