A lot of people are upset right now.  Please just stop and take a breath.
Do you recall several years back, when South Park did a post-Election episode?  Half the town was celebrating, and the other half was convinced the world was about to end.  And it didn't.  For the most part, nothing really changed.
The same thing is the most probable outcome here. 
And don't be angry at your neighbors if they didn't vote for her.  They are the same people they were Monday.  The same people they were 8 years ago, or 16 years ago.  They just didn't like her, or were tired of Business as Usual Politics.
Most Americans are moderates.  Most of us are conservative on some issues and liberal on others.  The Big Two parties are becoming more and more polarized.  They are reaching the point where they can barely talk to each other, let alone come to a reasoned compromise on any issue.
Don't see this as a bad thing.  See it as an opportunity.  Let's build some bridges.  Let's see if in 2020 we have a candidate or two that actually are worth nominating - let alone electing.
And, if you are of a religious bent, let's pray that Trump surprises us, and is actually competent.
