PHILADELPHIA – Hillary Clinton transcended her own flaws, and a spirited progressive insurgency, to become the first female major-party nominee in the 240-year history of the United States.“History,” Clinton tweeted at around 7 p.m., after her subdued rival Bernie Sanders rose from a seat in the Vermont delegation to request that all of his delegates, the hard-won token of his political life’s work, switch their allegiances to Clinton.The storyline inside the Wells Fargo Center was “chaos” during the first 36 hours of the Democratic National Convention, with the forced resignation of DNC Chairwoman Debbie Wasserman Schultz and talk of a last minute mass rebellion by renegade Sanders supporters.
