While the Democrats sweat it out over how voters perceive race and gender in this election, maybe it's time for the Republicans to take a look at how Americans feel about electing a 71-year-old man.

If John McCain wins, he will be the oldest person ever to serve a first term as president. And a new survey out suggests that the public might have more doubts about voting for someone of McCain's age for president than they would for an African-American or a woman.

The NBC News/Wall Street Journal poll shows 72% of those surveyed say voters are ready to elect a qualified black candidate, 18% say they're not. Meanwhile, 71% say Americans are ready to vote for a woman, 20% say they're not. But only 61% say the voters are prepared to vote for a person over 70, while 29% say they're not. Not exactly encouraging numbers for McCain and the Republicans.
