Well, without reading the AP story about the 7 things to watch for impeachment, I can only speculate based on general knowledge of impeachments. One thing to watch could be the transparency of the investigation process. If it's not transparent, it can lead to doubts about the fairness of the impeachment. Another might be the international implications. Impeachment of a leader can send signals to other countries and affect diplomatic relations. And of course, the legal justifications put forward by those advocating for impeachment are crucial. They need to be based on solid legal grounds and not just political vendettas.
Since I don't have access to the '7 things to watch for impeachment ap story', it's hard to be precise. However, possible things might be the nature of the alleged wrongdoings. Are they serious enough to warrant impeachment? Another could be the support or opposition within the political parties. Some politicians might support impeachment for political gain, while others oppose it for loyalty or other reasons. Also, the media's role in shaping the narrative around impeachment is important.
