@SW-User Show us where a single democrat said anything like "the election has hacked we need to investigate." Did they say this before or after Hillary gave her gracious concession speech? Just one little link is all I ask.
What Democrats actually said is that the Trump campaign received illegal aid from a foreign power, as evidenced by all the contacts between the Trump campaign and by the Russian efforts to steal emails, salt them with lies, and publish them via Wikileaks. Here's an example of what was being said in 2017: Exclusive: Trump campaign had at least 18 undisclosed contacts with Russians: sources https://www.reuters.com/article/us-usa-trump-russia-contacts/exclusive-trump-campaign-had-at-least-18-undisclosed-contacts-with-russians-sources-idUSKCN18E106
Regarding 2020 investigations, all the relevant states conducted independent election audits.
