Obviously not a huge thing. Romney won't be winning Arabs.
What makes you think that?
One of my uncles on the Lebanese/Palestinian side of my family basically sums up all of the ground Republicans have lost with that demographic over the past decade. He's a very successful business owner, goes to church on Sundays
and Wednesday evenings, the sort of person you'd think would be a lock for Republicans (and once was). He was very strongly for Bush in 2000, went to a bunch of fundraisers for him, maxed out his FEC contributions, got invited to play golf with him and some other Texas GOP people. Voted for Bush again in 2004 but with little enthusiasm. I honestly don't know who he voted for in '08 but he has been very pro-Obama this year, posting stuff on FB, emailing people, etc.
