It says a lot about who and where you think you are...
In general:
Candidates who are behind go on the attack.
Candidates who are ahead stay positive.
Mitt Romney took a surprisingly subdued tone during the final Presidential Debate that focused on foreign policy. With discontent and criticism mounting on the Administration's actions and statements over the terrorist attack on September 11, 2012 in Libya, Iran's continued pursuit of nuclear weapons, and the Fast and Furious debacle in Mexico - there was plenty of ammunition for Romney. Following acrimonious tenor and attacks of the previous debates after Denver's first debate - many were surprised when Romney declined to attack Obama as forcefully.
The only Romney attack that resembled the previous debates came when the Governor explained his characterization of the Obama's trip overseas as an Apology Tour:
"Mr. President, the reason I call it an apology tour is because you went to the Middle East and you flew to — to Egypt and to Saudi Arabia and to — to Turkey and Iraq. And — and by way, you skipped Israel, our closest friend in the region, but you went to the other nations. And by the way, they noticed that you skipped Israel. And then in those nations and on Arabic TV you said that America had been dismissive and derisive. You said that on occasion America had dictated to other nations. Mr. President, America has not dictated to other nations. We have freed other nations from dictators."
