Yet, experience shows that being consistently in the lead as Hillary Clinton has been essentially continuously for many months, also has its dangers. Some of these are described in my sister blog, Democratic Campaign Watch.
The Clinton campaign claims that Donald Trump is now spending money he has been hoarding for weeks. I have not had a chance to review the figures yet. However, I do know that no matter how deeply unpopular Trump is, his core supporters are aggrieved and motivated. These supporters coupled with millions of dollars raises important concerns in my mind. Some of these concerns having to do with Trump's fascist tendencies have been explored here previously.
The big danger now is complacency on the part of Clinton's supporters. Ms. Clinton will continue to need money for organizing and media. The history of this campaign shows that Clinton does best when directly contrasted with Trump as during last summer's conventions and the debates. Absent this kind of contrast and exposure, Clinton has done somewhat less well. Thus any complacency could -- at its worst -- represent disaster.
