You wish to create a Political Party of Saints and Angels who will do exactly what you want, 100% of the time?
Your problem started back in the Garden.
Your problem is with original sin and the fallen nature of man.
The political process is not perfect.
No political party will ever be perfect.
However, if you can not control the Republican Party with the level of perfection, purity and ideological correctness you wish, HOW ON EARTH WILL YOU EVER HAVE THE VOTES TO CONTROL THE ENTIRE ELECTORATE?
It is not the role of politics to affirm your identity, your ego, or pump you up, emotionally.
The real purpose of politics, in a free society, is to avoid armed rebellion.
You seem to prefer armed rebellion, as you refuse to participate, in any rational way, with the current process.
Rationality has absolutely nothing to do with voting for trash like Romney. Conservatives absolutely REFUSE to vote for Robozombie or for Obozo: for precisely the same reasons. To make believe that there are meaningful differences between the two of them is what violates both rationality and integrity.
