Of course you are right. I wasn't saying that it mattered what their background was, just questioning how it suddenly became "Palestinian." After all, back when they came to this country, the term Palestine wasn't in use. That said, I once had some dealings with the father, and can tell you that he was rude and obscene beyond belief, and acted this way even towards women when he was Governor. He entered the Mensa society and put a copy of the certificate on the wall of his office in a pathetic attempt to try to impress people. His temper and vengefulness were well known to all who dealt with him, and finally resulted in someone at the White House shooting him down with press leaks about his use of official limos on personal business. This was after he tried to control who could ride the helicopter to Camp David. After my run-in with him in his office, I felt that I had escaped some sort of Middle East hostage situation. Of course, that has nothing to do with the son, who by all reports is a fine fellow.
If my [admittedly old] info is correct, the present Mr Sununu had a grandfather, also called Sununu, who immigrated to the United States in the post- WWII era. This man was definitely a Christian, and gave his nationality as Lebanese when he entered the USA.
It appears his family did have some Palestinian connections however.
On the other hand, it would appear that the mother of the present candidate was/is a white Christian [RC] American woman from New England, not of Middle Eastern descent.
The grandmother of the present candidate is also shown as a white Christian [RC] American, not as having come with her husband from the Middle East, or having come here to marry him. In fact, it is not even said that SHE was of Mideast extraction, though she may well have been.
