The netroots is the real world of politics. Polls have shown (Hotline '06) that a strong plurality of Democrats read blogs and nearly all of them (Pew) vote; we are a majority in primaries.

Hi Jerome, can you provide links for these 3-4 claims, please?

You can't say anything about pluralities in a vacuum. A strong plurality of Democrats read blogs, as opposed to what? And how big was the plurality? A plurality can be 49% or 5%.
