WASHINGTON (Reuters) - Henry Paulson, a Republican who was U.S. Treasury secretary during the 2008 financial meltdown, on Friday called a Donald Trump presidency "unthinkable" and said he will vote for Democrat Hillary Clinton.
Paulson joins a growing list of establishment Republicans who say they will not cast a ballot in the Nov. 8 election for Trump, the party's presumptive nominee and a political neophyte whose populist rhetoric runs counter to many long-held Republican principles.
