8. Trump will do anything to stay in power. We already know that Trump is a liar. As the impeachment process plays out, Trump's lies will become more extreme. (For example, his claim that the Kurds are worse than ISIS.)
We already know that Trump will insult his opponents. As the impeachment process plays out, Trump insults will become more extreme. (For example, calling Speaker Pelosi a "third-grade politician" and saying she favors ISIS "because they are communists.")
We already know that Trump will use false claims of executive privilege to keep Administration officials from testifying before Congress and to deny lawful document requests. What else will Trump do? At the moment, there seem to be no limits to extreme behavior.
9. Social Media will be an issue. Facebook is permitting Trump to run blatantly false ads and Twitter is allowing him to promote damaging lies. Democrats have called upon the social media companies to regulate Trump's online behavior but they are unwilling to do this.(https://www.washingtonpost.com/technology/2019/10/17/facebook-ceo-mark-zuckerberg-says-interview-he-fears-erosion-truth-defends-allowing-politicians-lie-ads/ )
10. The Supreme Court will be involved. Even though many Trump-Administration insiders have begun to testify before the House Intelligence Committee, there are others that have declined to do so -- based upon Trump's broad assertion of executive privilege. In addition, House Dems are demanding access to the complete Mueller Report including Grand Jury Testimony. (https://www.washingtonpost.com/politics/courts_law/house-pushes-for-release-of-mueller-grand-jury-testimony/2019/10/08/a88a504e-ea3a-11e9-a329-7378fbfa1b63_story.html )
Both of these matters are wending their way through the courts and will likely be decided by the Supreme Court. Therefore, the conclusion of the House impeachment inquiry probably depends upon the Supreme Court schedule.
