For the last time, you cannot advance and ideology without a party. I would use charts and graphs but this is simple. In this case, you are wrong, wrong, wrong. Just look at history and that tells you that a party must be behind the ideology.
But the Republican party MUST represent limited government ideology. It MUST contrast itself from the Democrat party ideology of an intrusive, enslaving government that will always take care of you. The Republican party must represent the ideology that government is our SERVANT, that it must be limited, that free markets and personal liberty must prevail.
It seems to me that what you're saying is that as long as the politician is registered "Republican," then that politician is better than a Democrat. But the truth is that a liberal big government Republian like Romney who would have us enslaved to intrusive government is WORSE than a liberal big government Democrat because that Republican sabotages the future hope of a party home for that ideology that you and I hold so dear.
