Republican presidential candidates seemingly at odds with Bush over Iraq

From AP

"We cannot pull out and hope for the best," said Sen. John McCain, R-Ariz., calling redeployments now "a significant step on the road to disaster."

Sen. Sam Brownback, R-Kan., likewise dismissed a timetable: "We have to see this through to a successful conclusion."

But as we learned in last night's New York Times, Bush has seemingly approved a plan to establish a timetable for a partial US withdrawal from Iraq - albeit a very small withdrawal. So does McCain think Bush's new redeployment plan is a significant step on the road to disaster? And is Brownback upset that Bush apparently is no longer interested in seeing it through?
