In danger of becoming a one party state? I think we're there. Most Americans look to the government to solve all of their problems for them. Few if any show any sort of self-confidence to address their own problems themselves. R or D, we have consistently ceded freedom and liberty, in the hopes that whoever was in office would "Just make all the bad stuff go away". We're sheep, and we've gotten what we deserve.

If your question is whether the Democrats are approaching a permanent majority? Again, with the way the media editorializes on politics, and presents current events in ways that would make Pravda blush, the answer is a resounding yes. What's more, I don't see much hope for the fiscally conservative wing of the Democratic party, the Blue Dog Democrats.

Or haven't you heard about Accountability Now and Campaign for America's Future, two groups who are dedicated to targeting Democrats in primaries that "aren't liberal enough". Looks like your big tent is getting a little snug there too.
