Reading Yoda's blog about the future of the GOP and the comments on it regarding what the Dems are (or are not) doing to keep theirs reminds me of an article by former Texas House Speaker, Liutenant Gov. and Democratic lion-Ben Barnes. The article is focused on Texas politics but could be extrapolated to include the national Democratic Party:

The following quote, I think, distills the message nicely:
"Yet, regardless of whether a new Speaker is elected, if the House fails to focus on the serious issues confronting Texas, it runs the risk of becoming irrelevant. The power of being of being the majority party is often accepted as the simple answer, but it really isn’t. I’m all for electing a Democratic majority to the Texas House, but the above considerations must fit within our overall strategy of moving Texas forward. The strategy for winning back the Texas House cannot be predicated on winning a Democratic majority alone."
