McCain: Add 20,000 Troops

While in Lancaster this evening Senator John McCain said that the United States should sent another 20,000 troops to Iraq. However, he also said, "It's not just a set number." McCain has been calling for more troops since the insurgency started in 2003. Senator McCain's trump card is that as a former Vietnam POW, and member of the Armed Services committee, no one can question his foreign policy credentials.
