Votes only count if the people you vote for can be counted on. Those people are often very thin on the ground, hard to identify (it could be a political masquerade) or are unelectable because the voting majority don't like them.
Then, at least don't vote for candidate who makes a campaign point out of mocking science and promoting quacks in key public positions. That's something that most people could do.
Petroleum is a multi hundred billion dollar industry in the US alone. Attempting to vote our way out of this problem is in vain when considering the influence/ownership of the oil lobby on the political system.
