Except they are using their ethnicity as the selling point and they also want separate group i.e. the Hispanic Caucus or the Republican National Hispanic Assembly for example. Their ethnicity is prominent not their 'conservative values'.
No, but they’re doing it in response to a lot of hostility directed against Hispanics by conservatives, who seem to think of them all as illegal aliens. Bloc voting has always been exploited by the Dems, and the only way to break up that bloc (because once people think of themselves as being part of a particular voting bloc, they cease to think about the issues and only vote with their bloc) is to create a sort of mini-bloc so that people from a targeted group can identify with it and perhaps be attracted away from the Dems. We need voters!!! We need a fraud-proof margin.
