Obama campaign manager David Plouffe emails supporters this morning with the news that Obama has raised an extraordinary sum in September: Over $150 million.
The Obama camp added 632,000 new donors, bringing the campaign's total number of donors to over $3 million. Also extraordinary: The average donation for the month was less than $100.
The key here is that September was when the contours of the current context first became truly visible: The GOP convention took place at the start of the month, and hockey mom/pitbull with lipstick Sarah Palin was first introduced to America as John McCain's choice for backup commander in chief.
What's more, as the month unfolded, it became clearer and clearer that McCain had made a strategic decision to wage a campaign dominated by slimy attacks, vile adver-sleazements, and cosmic levels of mendacity. And Obama's donor base responded in kind, as did more than half a million newcomers.
Late Update: Plouffe's video announcing the decision to supporters is here.
