Romney continues to use the word "foreign" to describe the president's worldview. Yesterday:
"It’s a very strange and in some respects foreign to the American experience type of philosophy."
If you don't think this is calculated to trigger thoughts of Birthers and socialism/communism and so forth, you're naive. It's not the first time he's done this, and in the context of the McCain 2008 dog-whistles ("pals around with terrorists") and Romney surrogate Sununu's rants the other day, this is absolutely a calculated and coordinated use of the word.
