Sen. Sam Brownback's decision to endorse Sen. John McCain could wind up helping McCain in Iowa more than rivals expect.

## With Brownback's departure from the race, the grassroots infrastructure of the Iowa Christian Alliance was Mike Huckabee's for the taking.

Brownback could help prevent Huckabee (or Fred Thompson) from earning the group's endorsement.

## Brownback's precinct captains in Western Iowa could become McCain precinct captains

## And Brownback will work the state and stump on McCain's behalf. That's important, because Rudy Giuliani's biggest surrogates in Iowa -- Steve Forbes, who still commands respect here, and Jim Nussle -- are either unavailable to campaign for him or .. in Forbes's case, simply haven't.
