Questioning a candidate’s age and health is in bounds when determining the validity of a presidential run.
"Age is very legitimate issue for a presidential candidate, and whoever the eventual nominee nominees for president are, they go through, you know, a physical that's released the to the public. So it's an appropriate question," Huffington Post reporter Arthur Delaney said Friday. "You don't want somebody to be sick and die in office."
Many candidates in the past have been questioned if their age disqualifies them from running for office, most of them Republicans. Ronald Reagan was called too old to be president. Bob Dole was portrayed as out of touch and from a different generation.
More recently, John McCain received harsh criticism from the Obama campaign for not being able to use a computer. When Sarah Palin was tapped as the Republican vice presidential nominee, Democrats made famous the phrase "One heartbeat away from the presidency." The attacks on McCain were effective enough that he brought his mother along to a number of campaign events to tout her good health.
