I would say much of this has to do with scientific literacy on both sides of the issue.
Conservative mindsets are drawn to single enduring truths and absolutes. As scientific knowledge proliferates and becomes more publicly accessible, we're increasingly aware of the chaotic, occasionally conflicting, and ever changing nature of science. As there is no such thing as settled science, there's a pushback against the field. Especially as the role of politics is increasingly more evident. This is neither a good nor a bad thing - it just is what it is.
Liberal mindsets are drawn to a variety of truths and perspectives, with individuals deciding which truth or evidence fits their world view the best. As scientific knowledge proliferates and becomes more publicly accessible, the are more perspectives for liberally minded individuals to latch on to and agree with. There are attempts at consensus, but individual preferences still hold sway when it comes to what is and is not accepted. This is neither a good nor a bad thing, but it is not generally something I find preference with.
The scientific community has been able to hide behind its complexity and general awkwardness for centuries. The scientific community as a whole is going to have to find a better way to communicate their findings in a way that is neither condescending nor difficult for the layman to understand. It must also find ways to help the general population to see research in context without trying to do the thinking for them.
