I just saw this article in the Boston Globe, which I thought was unusually well-done for that newspaper. The basic point is that, while Mormons are generally conservative, they have key differences with evangelicals and conservative Catholics. Mormons are less likely to oppose abortion in all instances, they are more likely to support stem cell research, they are more likely to support the teaching of evolution in schools and they don’t get as riled up about the prayer in public schools issue. In general, given the Globe is a liberal newspaper, the article is complimentary (“those Mormons are not as crazy as those Neanderthal evangelicals” is the general tone).
The article even points out that Mormons are much less likely to get politically-tinged sermons at church.
In general, an article well worth reading.
