You mean the 18 million Hillary supporters won't be as generous donating to Obama as they have been to Hillary? If there were 18 million people that passionate about Hillary, she wouldn't have all of this debt, because she could pay it back with $2 each from her 18 million adoring fans.

Most of those (under) 18 million people who voted for Hillary were rational voters who preferred Hillary, and then moved on to support their party's nominee when their preferred candidate lost. The few thousand PUMAs won't vote for Obama under any circumstances, because they aren't Democrats.
