Need to nominate a candidate designed to appeal to moderates, that is.
If there are two lessons that we as a party and as a movement should have learned from 2006, they are the following:
(1) Republicans do not succeed when they abandon First Principles. Losing the high ground on spending, ethics, and leadership cost the party dearly in last year's election -- yet we seem to have largely forgotten that already (or to have projected blame for that loss onto other issues, like foreign policy).
(2) Republicans do not succeed when they campaign as, or nominate people who are, Democrat-lite.
