Whether certain presidential candidate likes Bitcoin or not, I'm quite sure that being publicly bullish on Bitcoin would pretty much be suicide election-wise. Simply put, a lot of Americans still think that Bitcoin is a scam, and being bullish on Bitcoin is one of the ways to not get you elected.
They just need to communicate it a bit better than me. Say things like "Hey inflation is bad. Housing and food is more and more expense. We need better currency like bitcoin".
Most americans already know about bitcoin these days after elon musk and michael saylor so are more friendly. Around 1 in 3 americans have owned some bitcoin at some point. Even those that didn't own already are curious.
