Highly encourage it! If it feels intimidating, you also can try to get some friends and or family to go with you too (plus getting even more impact with more people)
Polls do matter. They are a valuable way for ordinary people to see how the election might be going right now and to get an idea about how the population feels. Obviously though, nothing in politics can ever matter as much as voting.
I agree that's the intent, however, they too often can be misleading, used in misleading ways, or simply misunderstood. I think too many people sat at home in 2016 saying "Well, Hillary has this one in the bag." Let's not do that to Kamala Harris, and more importantly, to ourselves.
People like reflected glory, which they get by rooting for the "winning team."
You see this when people with no investment in a sport pick a team to root for in a big game. It's generally who they think will win, even if that guess is just based on vibes.
How many Germans with this mindset rooted for the Nazis, I wonder? It's one thing to root for the top dog in a sports match but it's unprincipled in politics. It's another level of ignorance and irresponsibility.
