Per the work of Cook Political Report’s David Wasserman, Obama’s national lead over Romney continues to expand as votes keep coming in. It’s now Obama 50.9%, Romney 47.4%. That’s a bigger (and more decisive) margin than Bush’s victory over John Kerry in 2004 (which was Bush 50.7% and Kerry 48.2%). What’s more, the president’s lead has grown to close to 3 points in Ohio, 4 points in Virginia and 6 points in Colorado. THE SECRET SAUCE in the Obama campaign’s fundraising emails? Brevity. “Obama’s email fundraising team tested hundreds of grabby subject lines. The most successful — ‘Hey’ — brought in millions of dollars,” Bloomberg BusinessWeek’s Josh Green reports. “The campaign would test multiple drafts and subject lines — often as many as 18 variations — before picking a winner to blast out to tens of millions of subscribers. When we saw something that really moved the dial, we would adopt it,” says Toby Fallsgraff, the campaign’s email director, who oversaw a staff of 20 writers.
