There's cause for concern in Hillaryland, the constellation of Democratic advisers, supporters and politicians counting on the former secretary of state to lead the party to a sweeping victory next November.
Hillary Clinton's nomination is almost a forgone conclusion, barring any unlikely legal or health issues. Democrats will offer a more coherent and unified front for the general election than fractious Republicans.
Still, this optimism is based on the weakness of the opposition, and ignores the candidate's own glaring vulnerabilities.
The worries of some Clinton insiders are focused on the general election. There is an "enthusiasm gap." She doesn't excite important constituencies: young people, independents, possibly even minority voters.
To be sure, a number of women, especially middle-aged ones, are energized by the prospect of electing the first female U.S. president. That's a strong asset.
