In 2020, nationwide according to the census bureau, of registered voters:
34% identified as Independent
33% identified as Democrat
29% identified as Republican
I'm going to guess that the 34% independent probably leans a single percentage or two towards the Democrats, so population wise the Democrats have the Republicans beat on numbers.
Square miles of land, the Republicans have the Democrats beat, but dirt doesn't vote.
Having no party affiliation, you get to hear and see things from both sides. The 3 big issues I heard people talking about was economy (inflation and wages), abortion (not happy with recent supreme court decision), and the war between Ukraine/Russia (concerns a GOP controlled house/senate would reduce funding). Oh, of course Trump being Trump probably didn't help the GOP either.
