I disagree, I think there are some clear ideologies. Support for women choosing whether to have abortions is in one camp, support for so called unborn children is in the other. Diversity is in the dems of course, the Republicans want to protect and emphasize the "traditional white american culture". I'm trying not to be pejorative to either side. There are negative influences that lead to them to have similar views, like the influence of say wall street money has both sides supporting big banks, I think this is what you are really getting at imho when you say there is no ideological differences.
