WILLIAM B. RICHARDSON
Richardson was one of a few Westerners who, at the time, had experience negotiating with the North Koreans, and one of the very few who ever got anything from the negotiations.
He was referring to the proposal to erect a fence between Mexico and the United States to stop illegal immigration.
McCain had been an independent-minded Republican, but when he first tried for the Republican Presidential nomination, the conservatives of the party trashed him for being too liberal. So when he ran again, he changed many of his positions to make himself more acceptable to the right wing, This was sufficiently effective to gain him the nomination, but as this quotation illustrates, many other Americans who had admired McCain for his independence, then became worried that if he were elected President, he would follow many of his new (flip flopped) positions. So many felt that way that he lost the election to Barack Obama. The shoe reference was to the fact that McCain and his wife were very wealthy and he wore expensive clothing.
