They didn't want any investigations being done. The news media that is a leftist propaganda machine said "It was the most secure election in history" Anyone who questioned anything to do with the election being stolen was brushed off as a conspiracy theorist, big tech. banned anyone that even mentioned it as a possibility, etc...
Countless leftist politicians claiming it was an absurd idea. Why didn't they just investigate? They loooooove investigations. Well except if it will show how corrupt they are, then it's all just conspiracy. If you want to take their word for it and think Joe Biden got the most votes in history, that's a you problem. lolz Maybe Joe Biden did and he is a way better president than Obama, it's just too bad Obama was holding back Joe Biden all those years. lolz
