It could just be one issue:
1) Drill, Drill, Drill. or
2) Some Reform theme that would resonate with the voters, like a pledge to eliminate ear-marks from their office. The senator would reach out to allies on both sides of the aisles, host an open discussion before the election, and challenge those running in the fall elections to make commitments.
It might be an early look at what they might be able to do later. If they do it right, nervous candidates will jump on Sarah's coattails to be dragged to victory. After the election, POTUS 44 will have some allies in both houses that saw the train coming down the track and got on before they got ran over.
But they need to get started. They need to be showing something new, something to reflect what will happen in their administration and they need to do it now.
Maintain the momentum, Stay on top of the wave.

I saw a televised McCain-Palin campaign rally yesterday where they were hammering away on both of those items. Even sounded believable.
