I watched the debate last night. It was clear that Newt was addressing the problems the nation faces while Santorum and Romney squabbled about their records. Today, Newt castigated Obama on Facebook:

It is an outrage that President Obama is the one apologizing to Afghan President Karzai on the same day two American troops were murdered and four others injured by an Afghan soldier. It is Hamid Karzai who owes the American people an apology, not the other way around.

Where were the other GOP candidates on this? Invisible.
