WASHINGTON, May 6 (Reuters) - Former Republican presidential candidate Jeb Bush said on Friday he would not vote for either the party's presumptive nominee

Donald Trump or the Democratic front-runner

Hillary Clinton in the November election.

"In November, I will not vote for Donald Trump or Hillary Clinton, but I will support principled conservatives at the state and federal levels, just as I have done my entire life," Bush, a former Florida governor, said in a Facebook post.

Jeb Bush joins his father and brother in refusing to throw his support behind the presumptive GOP nominee. Former President George H.W. Bush and his son President George W. Bush both reportedly don't plan to participate at all during the rest of the election season.
