With our current political system there is absolutely no chance. The people who rise to power are those that want power. That leads to massive corruption, and a string of shady events to keep said politicians in power by design. To that end it does not matter what science says to a large extent. The trick is fitting that science properly into an agenda.
The better question in my view is whether science can ever be properly presented to the public. Given the need to sensationalize the news, and how hard it is to interpret results this really is a thorny issue. Politicians will always bow to the demands of the majority. In order for politic and science to really work together you need the public to be informed about the science. Sadly, science is hard to understand so I do not see this happening.
