TOM STEYER: The billionaire environmentalist had flirted with the idea of running for the White House earlier this year but decided against it. Steyer, 62, a force in Democratic fundraising over the past decade, said in January he was focusing on his efforts to get Trump impeached and get Democrats elected to the Congress. He reversed course on July 9, saying other Democrats had good ideas but "we won't be able to get any of those done until we end the hostile corporate takeover of our democracy." His late entry underscores how wide open the Democratic primary field remains.
