If front-runners Donald Trump and Hillary Clinton lead their respective parties into the general election, the pair will be the oldest matchup in the nation's history,
The Hill reports.
GOP favorite, Donald Trump, will be 70-years-old on Election Day while the Democratic favorite, Hillary Clinton, will be 69-years-old, making the average age of a Trump-Clinton ticket 69.5.
In comparison, The Hill notes the average age of past presidential nominees has never topped 64 years.
But lawmakers and political experts on Capitol Hill say there is a reason why older candidates are not only running, but winning in the current race for the White House: "People are simply living longer and retiring later, voters have adapted to the switch," The Hill stated.
"There's a general understanding in this society that we are aging, as a society, and that 70 is the new 60," said Rep. Jim McDermott, D-Wash.
Before Reagan "you would have said that it's too late to run after you're 65," McDermott noted. "But not anymore."
Karly Bowman, a senior fellow at the American Enterprise Institute added that "having two candidates at this age in 1950 might have been significant," however, it is not significant in 2016.
And, Clinton backer Rep. Lacy Clay, D-Mo., said an older candidate tells her voters are looking for "someone with experience" especially "in these times — economic woes, unrest around the world."
Although both Clinton and Trump have released medical records proving they are fit to serve as the commander in chief, Trump has recently shifted his sights from the GOP primary field and has increasingly questioned Clinton's health and "stamina," according to The Hill.
"Hillary is a person who doesn't have the strength or the stamina, in my opinion, to be president," Trump told ABC's "This Week."
"She doesn't have strength or stamina. She's not a strong enough person to be president."
"Her command of issues, and her stamina, were the very things we noted. It couldn't be more false," Rep. Gerry Connolly, D-Va., who has endorsed Clinton, said of Trump's attacks. "I mean you can pick on her on some other things, maybe, but stamina is laughable on its face."
However, after Clinton fell and suffered a concussion in 2012, the incident triggered some in the GOP, including ex-Bush aide Karl Rove, to question her health going into the 2016 race, reports The Hill.
