Democrats love to talk about diversity but it was one of the main things missing from the first debate of the party's presidential hopefuls. In a party where youth, ethnic diversity and gender are touchstones, the party fielded five white candidates with only one woman and only one contender under the age of 60.

Martin O'Malley may look youthful standing on stage with Bernie Sanders, 74, Jim Webb, 69, Hillary Clinton, 67, and Lincoln Chafee, 62, but he still clocks in at more than a half century, having turned 52 in January. Sanders could claim the diversity card hailing from a family of Jewish immigrants but there is no doubt the entire Democratic field is old and white, something the Dems often deride.

In contrast the Republican field seems like a true cross-section of America. Currently Donald Trump, the frontrunner, is followed by Dr. Ben Carson, an African-American; Marco Rubio, the son of Cuban immigrants; and Carly Fiorina, a woman who worked her way up from being a secretary to the executive suite of one of the top tech companies in the country.

You can also add to the mix Ted Cruz, an Hispanic, and Louisiana Governor Bobby Jindal, whose parents immigrated to the United States from India not long before Jindal was born.

While Democrats talk diversity, the Republicans are living it without talking about it.
