When you hear news that one of the swing states have "certified" the victory for Biden, take it with a YUGE grain of salt because it might not be OFFICIAL. Examples:

Michigan - Sec of State said that the country canvasser certified. REALITY: the canvasser may not of signed the official documents. And even if she did, signatures might not be legally binding if the signer was coerced.

Pennsylvania - the governor (or Sec of State? I can't remember) said that the results were certified. REALITY: the judge who is currently halting certification said that she didn't received the official documents.

Same old shit tactic when the media called Biden the victor: they totally disregard the official/legal requirements to confirm it.

Main lesson: don't give up! You never know if there are more legal steps to make things official.
