Richard Nixon, you only show the Biden/Trump percentages. Look at the "undecided" percentages and ask yourself what proportion of those would vote for either candidate.
Also ask yourself what is a more likely lie to a pollster "I will vote for Trump" when in fact you will vote for Biden or "I will vote for Biden" when in fact you will vote for Trump.
Ask yourself, how many people stating their voting intention will actually follow through and vote. Will Biden-intending voters follow through at the same rate as Trump-intending voters?
How you answer those questions can be driven by ideology if that's what you want.
If you want to be closer to the truth then answer the questions based on logic. It's no secret what I think and I'm pretty sure I'm right.
