Fourth, the GOP already owned the energy issue and and the energy issue dominates and will continue to dominate the next 60 days. Even if Sarah Palin doesn't persuade John McCain to come out for exploring ANWR now, a vigorous exploration/conservation strategy has an ideal spokesperson in Palin.

Fifth, she is not a Beltway Republican. The modern GOP is the party of Reagan and Bush --both westerners, and very outside-the-Beltway. Neither ever succumbed to the Beltway's many poisons.

John McCain is clearly outside of his party's recent tradition, much more of the Eisenhower, above-partisanship nationalist than the movement conservative, comfortable as a Beltway big, on easy terms with the permanent political elite of the country from both parties and the Beltway-Manhattan media elite.

McCain, of course, understands the war and is the steel for the next crucial few years of resolve that victory in the war requires. A Vice President Palin will be a voice for the conservative movement in the Administration and for the party outside of the Beltway. The long run of Congressional power drained a lot of the energy from the GOP when it came to the battle of ideas, and Palin is a representative of the non-Beltway GOP that wants very much to get back into that fray. Winning the war remains the first priority, and Supreme Court justices after that, but on a host of key issues Governor Palin represents the reagan wing of the party, and that's a great thing.

Sixth and finally, she is young enough to be a bridge to the next generation, and with five kids, she has been living in the world of young moms and technology-dependent teens. This advantage will be hard to quantify, but when she is out on the trail talking about her kids and her family's path, it will be a huge counterpoint to the Obama's narrative, one that underscores that millions of American families are conservative, traditional, proud of their country and full of optimism about the future if the government's burdens do not grow to large and the country's enemies are kept in retreat.

There is a lot of enthusiasm out there, and given these reasons, it will endure until November.
