| Our exclusive Forecast predictions show Joe Biden padding his delegate lead in a big way on Tuesday. In normal times, advice for Election Day might be to bring your driver’s license, know your rights and carry snacks and water in case lines run long. But since these are not normal times, the state of Washington released an extra advisory last week: Please, don’t lick it. “It” being the state’s vote-by-mail ballot, which was sent out in mid-February … before coronavirus panic gripped the state. The viral turmoil, entirely mail-in vote and switch from a caucus to a primary makes the outcome hard to predict, but Washington could well be a tipping point for Sen. Bernie Sanders' campaign. According to our exclusive Forecast prediction model, former Vice President Joe Biden is now the heavy front-runner across the country — and is ahead in Washington, one of six states voting today and a place that should be Sanders country. If the insurgent loses here, it’s hard to see how he can mount a comeback. |
