Beyond which, that whole "Yee-haw, look it here! I can't speak the English right and got me that there ten-gallon hat and some of them cowboy boots 'yall " schtick that a lot of Southern Republicans have is absolutely repulsive to most Jewish voters. Until they can fix that, the Republican Party will have about as much luck reaching out to non-Orthodox Jewish voters as Snowstalker 
This probably has more to do with repulsion toward the South in general than it has to do with any actual actions of Southern Republicans. I mean, most GOP Congressmen from the South don't actually strut around DC in cowboy outfits...that's just what comes to mind when you think of the South, so you associate that with Southern politicians. Likewise, most Southern politicians don't actually brag about how they can't speak English, you just associate the South with illiteracy so that's what comes to mind when you hear a Southern accent. It's similar to how people associate Jews with lawyers, financiers, etc.
