Is the end of the Democratic party in the near future?

In my opinion the machine has self destructed, as it failed to pacify the majority, it did succeed in pissing off the majority who woke up in an angry mood, yet the democrat's are arrogant and so far removed from the main stream that they may very well cease to exist in the near future. When candidates leave town and decline the endorsement and campaign appearances by a sitting president of their party it is a tell tale sign that they are in deep trouble
