Media cocoon doesn't matter. No one's telling the Dems to break their media cocoon.
Trying to "fix" the losing party after every election has become tiring. See the Dems in 2004 and 2010, GOP in '06 and '08. The GOP lost because it had an inferior operation and an inferior campaign controlling the top of the ticket.
I'm sorry but the GOP media cocoon is a huge problem for the party. Right wing media created a false universe that thoroughly convinced Republicans that their views not only were right, but were also shared by the vast majority of Americans. It created a false sense of security. They figured they were doing everything right and didn't make the changes necessary to win the election, As it turns out, most Americans were very much against their agenda.
Right-wing media didn't create the false sense of security. Almost all of the polls were wrong, Republican-friendly or otherwise.
If you say so...
