There is tension between the traditional conservative GOP and the anti-spending Tea Party over the role of defense spending. The New York Times reports:
Those differences were on display Wednesday on Capitol Hill, where the traditional Republican who now leads the House Armed Services Committee, Representative Howard P. McKeon, fought back against proposed cuts in the Pentagon budget even as fledgling committee members supported by the Tea Party said that the nation’s debts amounted to a national security risk.
The discordant Republican voices on military spending have bred confusion on Capitol Hill, among military contractors and within the military itself, where no one is exactly sure what the members backed by the Tea Party will do. It also shows why taking on the military budget will be so hard, even though a widening deficit has led the president and the leaders of both parties to say this time they are serious.
