From article:
"What Democrats ought to do is look at guys like the Salazars and how they won," said Al From, head of the centrist Democratic Leadership Council, which helped put Bill Clinton (news - web sites) on the path to the White House in 1992.
He and others say the brothers' campaigns are possible blueprints for making inroads in the West and other traditionally Republican states.
They seem to have won by using a mix of family values and a pro-worker economic message.
On edit: Aside from being pro-free trade, which would modify the "pro-worker economic message," and being pro-death penalty, I think it largely stands as far as Ken Salazar is concerned.
