Election question

Here's a hypothetical:

Suppose you're running for Senate in a red state. Your success depends on winning an overwhelming number of the votes of the highly-educated urban/suburban part of your state. These voters are socially liberal, yet fiscally conservative. They respect military experience, yet are skeptical of the current administration's war in Iraq (more than the average American voter, even). Yet they're affluent, willing to vote their pocketbooks, anti-tax, and generally anti-union.

You, as a candidate, are a former Vietnam veteran, who has been an early and articulate critic of the war. You're also concerned about economic injustice. Your opponent has been an early and aggressive defender of the war. Do you (a) run on the war or (b) run on your vision of using government to address the inequalities of wealth in our country? If you're Jim Webb of Virginia, the answer is (b), though I can't for the life of me figure out how you arrive at that answer.
