Lol no they don't. Rhetoric chases people's votes, the material outcomes are predetermined by the systems of capital ownership, because the solicitation of donations is still the largest determinate of election outcome (outside of incumbency). Regardless if you win or lose, you have to enact policies that benefit your donors, or potential future donors, and given that we are living in the largest historical wealth gap, the material interests of politicians is to rhetorically chase the populace, but actually enact policies that only benefit the wealthy.
As you have so aptly demonstrated, the absolutely piss-poor political education that people in the U.S. receive insures that we will continue to be taken on the ride again and again.
Also, we don't need to use any thought to reply to you, when you demonstrate so little insight.
I honestly think that Perot (whose politics outside of his anti-war stance are just as idiotic and self-serving as every other politicians) gave the DNC and the RNC enough of a scare to lock everything down and ensure that a third party would never even taste national election success again.
