Even if what you assert was true, she didn't take positions and didn't answer questions, okay? Do you think that the people who voted for trump did so because of his strong policy positions and they would have voted for her if they only knew how she stood on topic x?
I don't want to get into everything, but honestly Trump does a better job making it
seem like he has strong policy positions and branding them.
"No tax on tips"
"Build the Wall"
"Lock her up"
"Mass deportations"
"Kamala is for They/them, Trump is for you"
"Make America Great Again"
"Democrats love war"
If you asked the average voter about top policy positions of Trump, that probably name something from that list. If you asked them the same about Kamala, what would they say? I really don't know.
Now, you and I know he probably won't follow through on any of that stuff because he's lazy and easily distracted, but you have to admit he has been better at branding and marketing than Kamala was. Whether you consider that "campaigning" or not is up to you.
