In the bubble your contemporary conservative/Republican lives in, Jews actually do vote Republican in overwhelming numbers. The fact that they're consistently the 2nd most reliable Democratic racial/ethnic voting bloc, after African-Americans, cannot possible be true so that can just be ignored.
Semi-joking aside, it really just is the case that in the Village there's a narrative about Jews being swing voters or even Republican-leaning. 78% for Obama in 2008.
A short blog post is not the place for a full discussion of what a "racial/ethnic voting bloc" is. You probably know what I mean.
