No. No, 100% no. These are elected representatives privy to national security information. Not a single Republican representative, at least in the Senate, is under the impression the vote was stolen or rigged. They know full well, just like every state government who certified, just like every voting official who went over the results, just like every natsec operative who acted as a check on foreign influence, that this was one of the most secure elections in history and that no amount of bioviating from Republican morons is going to change that. They are saying it was stolen so they can restrict voting rights and prevent more Democrats from being elected, regardless of the electorate's opinion, because they are smarmy shitheels who want your rights stripped from you to maintain their grip on power.
