American tribalism

Been reading a lot of stories along these lines:

For these women, a unique, and most unexpected dilemma, presents itself: Should they vote their race, or should they vote their gender?

No other voting bloc in the country faces this choice.

Here's a thought: why not just vote for whoever has the best ideas regardless of race or gender?

This is the kind of stuff that makes me wonder about the long-term viability of democracy.
