Just find someone who is electable and the closest to your personel views and vote for him or her. A vote any other way is a vote for far worse.
Anyone can rise to power and become "electable". I would never suggest to anyone they vote for an individual based on power, money, or popularity, which I presumes means "electability". One should only vote for the person they feel would do the best job. Not on popularity/electability.
Suggesting that someone should vote for someone, just because others say the have a "better" chance, seems offensive, and I personally would never follow that advice.
