What makes Donald Trump seemingly invulnerable to political scandals that might derail other candidates?

According to Bill Maher's analysis, Trump's political resilience stems from the public's extensive familiarity with his controversial nature. Maher suggests that Trump has become such a well-known quantity that no potential scandal or negative headline could realistically knock him out of the race, as voters have already factored in his polarizing behavior and controversies into their decision-making process. This creates a unique political dynamic where traditional "October surprises" or damaging revelations lose their typical impact.
