Everyone is only interested in their agenda in politics, calling for additional research just happens to sometimes further a side's agenda. As of right now, the Democrats are the one's who want additional research in most situations, but that doesn't mean they want more research universally, and when studies have come back negatively (as they sometimes do), they are disregarded.

That said, there does seem to be an overall lack of trust in the scientific method among the political right, the reasons behind which being a bit more complicated than political efficacy.
