1. She didn’t advertise because she thought (correctly) that the MSM was cheerleading for her.
2. She didn’t campaign actively because a) she didn’t want to, b) she doesn’t like people, c) she is fundamentally lazy, d) she thought it was all locked up anyway and e) she was ENTITLED to be President.
3. She pi$$ed off half the country (us “Deplorables”)
Toward the end she relied on fake polling by the bigs.
