That's certainly their intention, but it didn't work in 2000 or 2004.
Now, consider that the news media has fewer subscribers/viewers today than in 2000.
Likewise, consider that our labor unions are smaller today than in 2000 (e.g. the AFL-CIO has lost over 6 million members in the past half-dozen years).
So the Democrats are repeating their same plays, but with an even smaller core than they had back in 2000 (when they lost).
What makes them think that they can win now?!
I think the MSM is loosing their following exactly for the reasons you outlined, and people have grown ever more weary.
The people are also finding other outlets....talk radio and the internet.
They knew something was wrong about the MSM but couldn't put their finger on it.
