I could just as easily be a moderate (D) or (I) but in my state and region, as a (R) I can cast a vote in nearly all of the significant races.<quoted text>
You certainly sound like a moderate republican
It might be different where you reside.
Here, Independent's cannot vote in primaries at all and in my particular congressional district there are few (D) candidates and they have a slim to none chance for being elected.
As a super voter I'm more useful to the political process as a (R).
