Har. That's a pretty witty one. It's like supporting Alan Keyes or Pat Buchanan for President. It's a tough job.
You've got it all wrong...it is like supporting Ronald Reagan rather than marching with the "electability" crowd that buys into the liberal gospel that those dreadful conservatives can never win while telling the republicans they'd better go for "mainstream" conservatives. To give you an example, Justice O'connor was considered a "mainstream conservative," which is laughable.
