I guess they did that in order to improve their chances of conservatives actually opening the video rather than just see an accurate title and saying no way in hell I'm watching that. Though I agree it's pretty slimy behavior, seeing a video titled "why Biden will win" that then goes on to regale his alleged corruption and the other false spins on his policies would also have been very bad form.
Still I think it's important to address the issues brought up in this video like the fact/claim that above the board countries such as S. Korea and Japan were (and are) able to avoid both the brunt of an economic crisis and a high mortality rate while the US has such an extreme mortality rate and an economic crisis.
