The president himself has also noted the dangers of weaponizing the impeachment process for political reasons.
If a Democrat ever becomes president during a time where Republicans have a majority in the House, they could face similar actions designed to get them out of office. If a Democrat becomes president during a time where Republicans control the House and the Senate, then they could very easily find themselves on the receiving end of impeachment proceedings.
Despite the significant backlash, Democrats continue to maintain that impeachment proceedings are not about disliking President Trump. Very few, if any, conservatives or Republicans are buying it.
