Kamala Harris STEALS Donald Trump's Policy Platform?

We're about 3 weeks into the Harris-Walz Presidential campaign in mid-August, and so far, the closest America has come to learning Dome's platform is that she stole Trump's no tax on tip idea?? Could a candidate no one has voted for in 4 years with the media holding gallons of water jugs for her campaign might just pull off the biggest Presidency hijack in American history?
