Disclaimer: I've been part of too many (federal, provincial and municipal) elections and referendums to count. I just love partisan politics.
This article in the May 2004 edition of The Atlantic Monthly is a great read. It's penned by Paul Maslin, lead pollster for the former Howard Dean campaign.
Readers will notice that Maslin identifies a number of reasons behind Dean's fall and not once does he refer to blogs and/or echo chambers. Thank God.
