Maybe I'm mistaken, but it seems to me that we have primaries in this state to winnow down our field of candidates, and the strongest usually survive.  So, the only way to get your desired result is to handpick candidates based on what demographic they meet, rather than their strength as a campaigner.  Or what they believe in.

And, if that's the case, I hope you are pretty good at picking people that have a good work ethic, that are quick on their feet, and are willing to actually work... and know the issues.

Oh, and have the right "look", and gender, and so on.  

Bean counting and quotas and cherry picking demographically 'right' groups aren't how you win.

Presenting a good case is how you win.
