Noam Chomsky is one of my heroes. I believe he is the leading voice in the United States for left-wing ideology. One might think that he would urge his followers to vote for the Green Party in the presidential election (since that is the farthest left of any of the political parties on enough ballots to have a theoretical chance of getting 270 electoral votes), but that is not what he's saying. He thinks it would be a mistake for American leftists to vote for a third party this year -- and he lists 8 reasons why that is true:
1) Voting should not be viewed as a form of personal self-expression or moral judgement directed in retaliation towards major party candidates who fail to reflect our values, or of a corrupt system designed to limit choices to those acceptable to corporate elites.
2) The exclusive consequence of the act of voting in 2016 will be (if in a contested “swing state”) to marginally increase or decrease the chance of one of the major party candidates winning.
3) One of these candidates, Trump, denies the existence of global warming, calls for increasing use of fossil fuels, dismantling of environmental regulations and refuses assistance to India and other developing nations as called for in the Paris agreement, the combination of which could, in four years, take us to a catastrophic tipping point. Trump has also pledged to deport 11 million Mexican immigrants, offered to provide for the defense of supporters who have assaulted African American protestors at his rallies, stated his “openness to using nuclear weapons”, supports a ban on Muslims entering the U.S. and regards “the police in this country as absolutely mistreated and misunderstood” while having “done an unbelievable job of keeping law and order.” Trump has also pledged to increase military spending while cutting taxes on the rich, hence shredding what remains of the social welfare “safety net” despite pretenses.
4) The suffering which these and other similarly extremist policies and attitudes will impose on marginalized and already oppressed populations has a high probability of being significantly greater than that which will result from a Clinton presidency.
5) 4) should constitute sufficient basis to voting for Clinton where a vote is potentially consequential-namely, in a contested, “swing” state.
6) However, the left should also recognize that, should Trump win based on its failure to support Clinton, it will repeatedly face the accusation (based in fact), that it lacks concern for those sure to be most victimized by a Trump administration.
7) Often this charge will emanate from establishment operatives who will use it as a bad faith justification for defeating challenges to corporate hegemony either in the Democratic Party or outside of it. They will ensure that it will be widely circulated in mainstream media channels with the result that many of those who would otherwise be sympathetic to a left challenge will find it a convincing reason to maintain their ties with the political establishment rather than breaking with it, as they must.
8) Conclusion: by dismissing a “lesser evil” electoral logic and thereby increasing the potential for Clinton’s defeat the left will undermine what should be at the core of what it claims to be attempting to achieve.
