From a statement by DNC chairman Howard Dean:

There is no question that the West is important to the future of the Democratic Party. The recent Democratic gains in the West exemplify the principle that when we show up and ask for people’s votes and talk about what we stand for, we can win in any part of the country. Additionally, we have a number of strong Democratic leaders in the West who will be a part of showcasing the vision of Democratic leadership for America as we introduce the next Democratic President in the Rocky Mountains.
