Former President George W. Bush and First Lady Laura Bush put to rest some intense speculation about where they aligned politically in the 2016 race.

NBC News has confirmed Tuesday that both voted down ballot Republican but chose to abstain for voting for the presidency two weeks ago, snubbing their party's nominee Donald Trump.

Trump has been highly critical of many aspects of President Bush's administration, particularly his controversial decision to got to war with Iraq in 2003. There have also been reports that George W. Bush's father, former President George H. W, Bush, would be casting his vote for Hillary Clinton on Tuesday.

The only living former Republican nominee to support Trump's candidacy is former Sen. Bob Dole. The 2008 nominee, Sen. John McCain, initially pledged to back the party's choice but rescinded his endorsement after a now infamous "Access Hollywood" audio tape featuring Trump making lewd statements about groping women.

The party's 2012 nominee Mitt Romney has long said he would never support Trump's candidacy, and delivered a blistering speech earlier this year detailing why he believes the real estate mogul is unfit.

George W. Bush, on the other hand, has stayed largely out of limelight and has completely eschewed partisan politics since he left office.
