Negative. A vote would be credited to Biden but the paper receipt would show a vote for Trump. That would be a one to one correlation. In actuality you would have to set some other flag so that only a portion of Trump votes went to Biden or else too high a tally for the dirt bag would give away the gamePlus what you're showing would be easily caught by simple math. Say we know that 1,000,000 people voted. To keep it simple 50% voted Trump and 50% voted Biden. This would lead to 500k each. However, with Biden getting a +1 that would jack the count of the machines up to 1.5 million votes, which we know is 50% higher than the number of voters counted.
So, if you had a million votes but one out if every 17 Trump votes was credited to Biden instead, you would still have a million votes but Biden would have just under 6% more votes than he earned
