Peter Beinart in The Guardian:Every now and then, a Senate race sets the direction for an entire party. He did it by promising to expand access to healthcare – and thus created a template for Bill Clinton’s presidential campaign the following year. If Abdul El-Sayed can follow up his victory in last night’s Democratic Senate primary by winning the general election in Michigan this fall, he will have created a template of his own. Despite his closer-than-expected margin of victory, his campaign offers a model for how Democrats across the country can answer the political challenge posed by Donald Trump. By casting the Michigan Senate primary as yet another battle between progressive insurgents and establishment centrists, media coverage of El-Sayed’s campaign has tended to overlook what is innovative about it.
