It is noteworthy that while endorsing Canova, and helping raise an estimated $3 million for his campaign, Sanders held back from actually going to south Florida and making a public appeal to voters there to defeat the incumbent representative, who was endorsed by Hillary Clinton, President Obama, Vice President Biden and a host of other top Democrats. It was a tacit message to the Democratic Party establishment that there are lines Sanders agrees not to cross.
Only days after the primary, Sanders sent out a message to his database of small contributors, some four million people, appealing to them to send money to four Democratic candidates in close contests for US Senate seats, in New Hampshire, Pennsylvania, Ohio and Nevada.
He claimed, "The Democratic Party passed an extremely progressive agenda at the convention. Our job is to make sure that platform is implemented. That will not happen without Democratic control of the Senate." A spokeswoman for the Democratic Senatorial Campaign Committee gushed in response, "We are excited to have Senator Sanders' help and support as we work to win back the majority."
The big lie about the supposedly progressive Democratic platform was the basis of Sanders' endorsement of Clinton in July. This platform, however, for all its small-bore pledges of modest improvements in domestic policy, is a full-throated defense of American imperialism, declaring that the United States must have the most powerful military apparatus in the world.
Sanders attracted the support of millions of youth and workers because of his claim to be a "democratic socialist" and his denunciations of economic inequality and the political influence of "the billionaire class." But he never voiced the slightest opposition to a foreign policy based on the defense of the worldwide interests of that billionaire class.
The ignominious fate of the Sanders campaign is a demonstration of the political fact that there can be no struggle against Wall Street at home without an open repudiation of American imperialism abroad, and the struggle to build an international movement of the working class against imperialist war, based on a socialist program.
