No, that is absolutely not how science works. There's a reason why scientists undergo a peer review process to publish papers, and why journals have an "impact factor" score: it's because they're not all equal, and it takes an incredibly long time to become established as credible inside of academia.
If you're referring to the casual layman bickering that happens in the peanut gallery surrounding certain scientific results, then sure, all kinds of people with ulterior motives jump on those kinds of bandwagons and flamewars. But the scientific process itself does not (or at least tries not to) work that way, thus serving as a counterpoint to the idea that "everything is political".
