No, it does not look the same.
Maybe Pelosi was hedging her bets at the time and needed plausible deniability in case something went wrong, so she grabbed some illegal alien guy at a local Home Depot parking lot and paid him $50 to forge her signature. Then, if Hawaii had ever blown up, she could legally claim that the signature sent in the fraudulent affidavit was not hers... some other temp worker in the Dem HQ must have signed it (a la the mortgage mystery ghostwriters with deeds of trust). Once Hawaii bought into the fraud and printed the ballots, it would have made a challenge in the public all but impossible.
I’m no handwriting expert, but they sure look the same to me. My signature certainly is identical from day to day and there seem to a few common elements that aren’t “standard”, e.g., a capital N that looks like a croquet hoop,a small n that looks like a u, a y “stem” that bends to the right instead of the left,a i that looks like Mt Fuji etc.
