In 2008, more than 550,000 gave more than $200 to Barack Obama, entering their names in the longest list of individual donors ever seen in American politics.

That list was a snapshot of the hope Obama inspired in a cross sections of liberals, young professionals, African-Americans, and Democrats who saw in him a generational and historic moment. But now, as Obama struggles to keep pace with his 2008 fundraising clip, that list offers a cross-section of Democratic disappointment and alienation. According to a BuzzFeed analysis of campaign finance data, 88% of the people who gave $200 or more in 2008 — 537,806 people — have not yet given that sum this year. And this drop-off isn’t simply an artifact of timing. A full 87% of the people who gave $200 — the sum that triggers an itemized report to the Federal Elections Commission — through April of 2008, 182,078 people, had not contributed by the end of last month.

Interviews with dozens of those drop-off donors reveal the stories of Democrats who still plan to pull the lever for the president, but whose support has gone from fervent to lukewarm, or whose economic circumstances have left them without money to spare. The interviews and the data are the substance of an “enthusiasm gap” spurred by the distance between the promise of the campaign and the reality of governing, one that has begun to deepen Democratic gloom about this November’s election.

“Where’s the change I can believe in?” asked Lisa Pike, a 55-year-old from Williamsburg, Va. with a small medical transcription business who gave $658 in 2008.
