Is it sexist to talk about Hillary Clinton's age?

Article here. Excerpt:

'Like Mitt Romney and John McCain, Hillary Clinton will (probably) run for president in 2016 as a grandparent. This seemingly unremarkable fact has triggered a spasm of media self-analysis: is Clinton the victim of a sexist double standard?

It's a question that has been -- and will be -- asked often.

We keep asking, because we refuse to see the plain answer. Hillary Clinton is not the victim of a double standard. She is the beneficiary of a double standard.

Consider the grandmother question. If elected in 2016, Hillary Clinton will be the second oldest president in U.S. history, after Ronald Reagan. At age 69, will she be too old? That was a question people felt free to discuss when John McCain ran for president.

CNN.com reported on June 15, 2008:

"Listen to some Democrats, and you'll think the 71-year-old Arizona senator is a man lost in a perpetual fog. He is 'confused' and has 'lost his bearings' or is 'out of touch.'" The "lost his bearings" innuendo was used by candidate Barack Obama himself, in a May 2008 interview with Wolf Blitzer.
...
In other words: as between Hillary Clinton on the one hand, and John McCain or Bob Dole on the other, the same standard is a double standard.

The same method applies to the discussion of Hillary Clinton's marriage. The Clinton camp's view seems to be: When it's helpful to Hillary, her marriage is urgently relevant; when that marriage might be politically harmful, it's sexist and insulting to mention it.

When Hillary Clinton sought the Democratic nomination in 2008, she argued that her tenure as first lady ought to qualify as a bona fide job credential. She told National Public Radio in March of that year:

"I represented our government and our country in more than 80 countries, and I know that people are nitpicking and that's fair -- it's in a campaign. But compare my experience, even after the nitpicking, with Sen. (Barack) Obama's. I mean, let's look at this objectively here, and I think my experience is much more preparatory for the job that awaits."

Yet when Republican likely candidate Rand Paul suggested that Hillary Clinton ought to be held to account for some of the scandals of her husband's administration, Team Clinton went into outrage mode. The influential columnist David Corn (Mother Jones/MSNBC) chuckled, "Paul's waving of the Monica flag has been dismissed by pundits on the right and left as odd and irrelevant. ..."
...
Hillary Clinton asks two things of us. On the one hand, she wants to be judged exactly as we'd judge a similarly accomplished man in politics. On the other hand, she wants us always to remember that the hopes of all womankind are fixed on whether she personally gets the job she wants. ...'
