No matter which side you're on, prudence - particularly in a race this close - suggests waiting until the process is complete before reacting to predictions. Some points to consider:
Neither the president, nor his challenger, nor the news media, nor the popular vote, nor rioting, nor social media determine who wins the presidency; only the Electoral College does.
We are still waiting on many outstanding votes, recounts, and litigation.
We must determine if we want every vote counted or if we just want our preferred candidate to win.
Many people celebrated through the Mueller investigation (thinking that was the end of Trump) only to be disappointed when it didn't end how they expected. The same people celebrated again after the impeachment only to be disappointed when the Senate acquitted him. It appears we haven't learned our lesson. Once again, I hear people celebrating rather than allowing the process to run its course. Don't count the chickens until they hatch.
How will those who are celebrating now react if Trump ends up winning (which is still very possible at this point)?
As Americans, we absolutely must have confidence in our elections. If we don't have a government of, by, and for the people, then we don't have a country. The integrity of the election process is incomparably more important than having one's preferred outcome.
For now, I will continue to watch and wait. I encourage all of you to do the same.
