Kathleen Hartington Kennedy Townsend, the daughter of RFK, claims the ex-president told her he's voting Democrat.
Former President George H.W. Bush, who lost a second term to Bill Clinton in 1992, will be voting for the wife of his former bitter rival, according to reports.
Kathleen Hartington Kennedy Townsend, daughter of Robert F. Kennedy, recently visited the 42nd president and later posted a picture of herself and Bush to Facebook with the surprising revelation.
"The President told me he’s voting for Hillary!!" the caption reportedly read.

The former Maryland lieutenant governor confirmed the news with Politico, saying, "that’s what he said."
Meanwhile, a spokesman for President Bush would neither confirm nor deny the report.
"The vote President Bush will cast as a private citizen in some 50 days will be just that: a private vote cast in some 50 days. He is not commenting on the presidential race in the interim," Jim McGrath said in an email to Politico.
The official response is in line with what many mainstream, high profile Republicans have done in the months since Donald Trump swept their primary and became the party's nominee.

Both George Sr. and George W. Bush have declined to endorse Trump but have refrained from publicly throwing their hat in for anyone else.
Neither Jeb Bush nor John Kasich has endorsed their party's candidate, either. And just this past Sunday, Republican National Committee chairman Reince Priebus warned they could suffer consequences for keeping mum.
"Those people need to get on board," Priebus told Trump's former primary opponents on Face the Nation. "And if they're thinking they're going to run again someday, I think that we're going to evaluate the process – of the nomination process and I don't think it's going to be that easy for them."
