The short answer is “We” wouldn’t. None of us (at least most of us) Do not have the the ability to investigate claims ourselves. Sure We can see a lcip claiming to show Discarded ballots for Trump as “proof” that those were illegally discarded or accept the explanation that those were improperly filled out therefore discarded, bu t none of us really know.
The longer answer is to put all the facts together and come to the more reasonable conclusion:
Scenario A. A President whose approval rating has never crossed 50%, who “oversaw” the deaths of hundreds of thousands in a pandemic that he admitted to have downplayed (if he was actually responsible for deaths is irrelevant) , where most economic markers are worse than when he started office (Not necessarily his fault), actually lost the election as was predicted by almost all polls going into the election. and in order to save face, as he said “I Don’t lose well” alleged fraud took place as he said he would before the election took place both in 2020 AND in 2016 as well as in primary races he lost.
or
Scenario B. The Democrats coordinated efforts to steal 6 states elections, but left the Senate in deadlock (not to raise suspicion I guess) lost seats in the house. Trump’s AG, head of election cybersecurity, as well as many Republican appointed judges not to mention most senators and congressmen, As well As Republican officials in those stolen states are in on to too.
Trump of course knew the election was being stolen, yet Inexplicably instead of hiring real lawyers to litigate these cases, perhaps people who specialize in election law (Like Gore and Bush did during a real case) Trump chose to hire incompetent Showboaters who are great and talking big but clearly were not going to deliver
Is scenario B POSSIBLE? of course!
is it more likely ? of course not
