(CNN) – Suddenly, everyone just wants to make sure Hillary Clinton is feeling alright.
This weekend more Republicans clung to the script first crafted by GOP strategist Karl Rove, questioning Clinton's age, and the blood clot she suffered in 2012. Such attacks, they say, will be "fair game" if she decides to run in 2016.
"She'll be 69 at the time of the election in 2016. If she gets elected and serves two terms she'll be 77," Rove told Fox News.
"Health and age is fair game. It's fair game for Ronald Reagan. It's fair game for John McCain," RNC chair Reince Priebus told NBC.
"Any presidential candidate, or vice presidential candidate is going to have to answer questions about their health," former vice president Dick Cheney told Fox News.
Several key Democrats defended Clinton on the Sunday morning talk shows.
"I think Karl Rove is struggling to be relevant," Sen. Claire McCaskill, D-Missouri, told NBC.
"In my view, she's in the prime of her political life," Sen. Dianne Feinstein, D-California told CNN.
So what does the back and forth mean for Hillary Clinton?
Roll Call's Christina Bellantoni and CNN national political reporter Peter Hamby weigh in.
