Is it sexist to ask how Clinton's grandkid will affect 2016?

You've probably heard by now Chelsea Clinton is pregnant with her first child. And odds are you've also probably heard some of this.

From CNN, "As Chelsea gets ready for motherhood, political circles are buzzing about how this might affect a potential Hillary Clinton run for president."

And MSNBC, "Could a baby in the Clinton family take Hillary out of politics?"

"Can we talk about the human drama that is Grandma Clinton?"

Of course, Clinton hasn't even said whether she'll run in 2016, but that hasn't stopped the speculation over how her daughter's pregnancy might affect her shot at the White House.

A writer at Time mused "the grandma card" could prove useful.

The Wall Street Journal suggested it would help with "softening [her] image."

Whereas Politico's Alexander Burns theorized Clinton's future-grandma status "may make the Iowa State Fair a less appealing place to spend the summer of 2015."

While the pundits debate what political ramifications Clinton's grandchild might have on her career, they've prompted an entirely new discussion: Would the same question ever be asked of a male politician?

Certainly in 2012 Mitt Romney didn't face the same scrutiny - despite welcoming his 22nd grandchild on the campaign trail. Probably because being president and being a grandparent obviously are not mutually exclusive.

So, why bring politics into what's otherwise an exciting time for Hillary Clinton and her family? Some would argue there's an element of sexism at play.
