"Mail in ballots, even absentee ballots have a built in inherent risk because they are uncounted ballots being transported."
States have confirmation systems. If you were correct, there would be lots of folks who complained of mailing in, but the system didn't confirm. Where are they??? Oregon, in particular, has 30 years of data you could check.
"Larger numbers of these such as millions is a higher risk..."
You have no proof of that, and the links above literally prove you wrong.
"... and I predict will lead to another catastrophe in a future election"
ANOTHER catastrophe?!? The "catastrophe" you're referring to is Trump's honest loss. The "catastrophe" was liars like you who made untrue claims. And FIVE YEARS LATER, you still have no proof...and you're calling it a CATASTROPHE?!?
You're just upset "certain" people got to vote who you wish wouldn't.
Ultimately, every legal voter should be able to choose the way they cast their legal vote.
"Opportunities to lose these uncounted ballots to accidents is an election disaster just waiting to happen."
Except those ballots are serialized and watermarked, and voters can confirm online whether or not their vote has been cast.
Now do the danger of Flying Unicorns eating mail-in ballots.
