Why is the 2016 Democratic field so old?

Two things, the Democrat Party is populated by both old, cold, evil, ego-driven and unattractive young people that are stale, boring, and could care less about the USA and “all” its people.....they care only about themselves and their political power, and, their beloved darling, POTUS Obama is destroying not only the USA...but....he actually is destroying the entire Democrat Party. Why? 2010, a political diaster for the Democrat Party, 2014, a political devastation for the Democrat Party....coming in 2016, with Clinton heading the Democrat ticket, a political wipeout for the Democrat Party!!! Talk about self-inflicted wounds!!! Hillary Clinton for POTUS??? Democrats are certainly not the sharpest knives in the drawer!!!

There are a couple more reasons not mentioned (related to each other):

The success of the tea party at the local and state levels has kept would be prominent Rat candidates off the field.

All the Blue Dog type Democrats recruited by Rahmbo to run in swing districts in the 90’s have been wiped off the slate in the past few elections. All that’s left are the old dinosaurs in safe blue districts who have held office for decades.

Because the younger commies in the party don't have the self control or restraint of the party elders, like Alan Greyson...

It’s not so much they are old as they are old self interested bitter control freaks who know better than anyone else. Not to mention, their only qualifications is, they have spent a life time working in the government!
Obama wasn’t even in the boy scouts and he only worked a very short time in the private sector.
Most of them could not function outside the bubble that is DC and/or the world of a lifelong politician.
Someone like Hillary despises ordinary people. They are foreign to her.
Yet, she knows she needs them to get elected. Democrats in general despise ordinary people.
To a Democrat/rino politician the most worthless person is a honest hard working person, with a modest income, who isn’t dependent on the government.
Otherwise, when they stand next to a “ordinary person”, for a photo op, for them it is like standing next to a mannequin or a space alien.
You are a vote bot.
You are from another dimension. The nether world of hard working American loving people who actually believe in something.

From your map.... just take California as an example...

If you look at the California map, it would be colored red mostly in terms of LAND AREA, unfortunately the map does not account for the fact that the small areas that are blue (San Francisco, Sacramento and Los Angeles ) account for MOST of the population.

The red portion is sparsely populated.
