The chances are 0%, because those accusations are made up.

You don’t need to take my word for it. Look at the lawsuits. The Trump campaign isn’t alleging mass fraud in court. And they’ve voluntarily withdrawn lesser allegations because their case was so weak. Here’s one example.

If they meant what they’ve been saying in public statements, if they actually had evidence for any of it, they’d put it into lawsuits too. But they’re not. They’re just saying it.

If someone tells you stuff when there’s no consequences for lying, and doesn’t say it in court were there could be consequences for lying, that’s a clear sign that they’re lying.
