"I think Harris deals in complex issues rather than soundbites and slogans which for me is a good thing"

you are just projecting competence onto this woman, and making her into some fantasy candidate
Let's look at some of the things she supported in the past, and then backtracked on, or completely changed her tune on
1. Single-payer healthcare. She said in 2020 that she wanted Medicare for all, and an elimination of private healthcare, because healthcare was a "human right". She said she was firm on this as a guiding principle. A few years later, her campaign tells us that she didn't really mean that, and intends to keep the private system in tact. So much for principles
