Obviously Romney was referring to the Mediterranean Sea. I'm sure he knows that Iran borders the Persian Gulf.
It is amazing to see people nit-picking over things like this when we're talking about a man who has balanced large budgets, who brought his state's unemployment rate down to below 5%, who increased his state's reserve fund, who cut property taxes for seniors, who balanced his state's budget four years in a row, who rebated over $270 million in taxes back to taxpayers, who increased the number of charter schools, and who proved time and again that he can work in a bipartisan manner--not to mention the fact that he turned around the SLC Olympics.
Why on earth would anyone want 4 more years of the misery we've had when we can elect a man with such a sterling record?
