You don't know how this works....
1. Democrat does bad thing
2. Media runs interference and downplays the story prior to the election
3. Democrat gets elected
4. Months later scandal is revealed
5. People complain, 'why didn't you tell me before I voted'?
6. Media just says yeah not really a big issue even though it's bad, unethical, illegal, whatever.
7. Nothing happens unless there is #metoo aspect
8. If in step 3 the democrat loses, then media will insist it's a big issue.
Pick a location, a time, an era, all the same. It's been like this for decades and decades.
