“We’ve identified,” she added, “at least 450,000 ballots in the key states that miraculously only have a mark for Joe Biden on them and no other candidate.”
What exactly is wrong with this? In an election with record voter turnout due to possibly one of the most polarizing presidents in history, is there really that much of a surprise that you're seeing a number of ballots that vote for Biden alone? How many are voting for Trump alone? I imagine there's a good number there too.
When you try to throw this into a discussion about election fraud, it gets stupid, because then you have to start asking "if you're already cheating, why wouldn't you help the down ballot Democrats as well?" They mention key states here, Michigan's Senate race was close, as was North Carolina's, and the two Georgia Senate races are going to runoffs so having more Democratic votes in any of those would have been helpful for their Senate chances. But this idea that these ballots show fraud assumes that they were fraudulently created, but then just ignored everything but the Presidential race. That's ridiculous given how important flipping the Senate and keeping the House was in addition to Biden winning.
It's far more likely that individual voters who don't know or care about the Senate/House races, but do care about the President given how polarizing this election cycle has been simply voted for Biden/Trump per their views on that and left it at that. I'll be honest, I barely knew anything about most of the people on the ballot when I voted. Beyond the President, I knew the Governor candidates and the incumbent Secretary of State (not his opponent), and knew my votes based off that. I did what research I could beforehand to make the rest of my choices, but if I'd just shown up and voted, it wouldn't have been insane to just mark those 3 and leave it at that.
This goes especially for people that don't identify with a party and thus wouldn't just mark Democrat or Republican on all candidates. They know who they want for the President, so they mark that and leave. That's not illegal, to my knowledge.
