- Jurisdictions with more votes than voters
- Dead people voting
- Individual alive people who claim to not have voted, being counted in the voter roll
- Literal videos of ballot counters marking ballots
- Thousands of "mail-in" ballots that have literally one mark, only for president, all in sequence of each other, without even being creased
- Thousands of claims of harassment and blocking of poll watchers
- Thousands of votes being flipped by the polling machines, all in the direction of Trump -> Biden
- Statistical analysis of the unlikeliness of the authenticity of the ballots in the contended jurisdictions, all of which stopped counting in the dead of the night, when they subsequently received mass piles of fresh ballots that leaned unrealistically heavily in one direction
- Non-enforcement of the only way to sort-of authenticate ballots: signature matching
- Not necessarily "evidence," but the unlikeliness of republicans winning literally every single hotly-contended house seat, yet losing support for the president
To summarize:
Trump knew Russia was trying to help him. He knew they wanted to offer dirt on Clinton in exchange for better relations. The hacked information was indeed delivered, meanwhile Trump’s campaign was funneling internal data to Russian Intel, which was attacking The election. And surprise surprise, the Republican platform that year was softer on Russia than it ever had been in the last 40 years. Suddenly Republicans don’t care about Russian annexation of Crimea? For no reason at all?
No evidence? Really? Let me guess, you only read the Bill Barr memo, which a Federal Judge has noted seemed to be intentionally misleading of the Mueller Report. I guess you also haven’t read the Senate Intel report, which lays out 900 pages of evidence related to Russian interference of the 2016 election, and the Trump campaign’s entangled involvement with it.
Maybe you don’t believe they colluded, but let’s remember that the original, official Trump campaign line was that they had zero contacts and zero deals with Russia. This turned out to be a complete lie.
