Vermont's Sanders Kicks Off 2016 Bid

Challenging Hillary Rodham Clinton from the left, Vermont Sen. Bernie Sanders kicked off his presidential bid Tuesday with a pitch to liberals to join him in a "political revolution" to transform the nation's economy and politics. Sanders, who entered the Democratic race in late April, formally opened his White House campaign in Burlington, where he was first elected mayor by defeating a longtime Democratic incumbent by 10 votes. Three decades later, Sanders is the underdog again, vowing to campaign on an agenda to elevate issues like income inequality, campaign finance and climate change. Sanders declared to about 5,000 supporters along the shore of Lake Champlain, "With your support and the support of millions of people throughout this country, we begin a political revolution to transform our country economically, politically, socially and environmentally."
