Crime rates always fall when people are working and jobs are plentiful, because people are under less stress and feel better about and themselves and their lives. Murder rates went up under Dotard because the economy collapsed under his watch, people lost their jobs, kids were home from school, and there was great uncertainty about whether or not people would live, work, lose their place to live, etc. President Biden, under his calm leadership pushed out truth about COVID, got shots in arms, got people back to work and school, and revitalized the economy, thats why crime rates went down, and continue to fall.
If people think their vote won't matter they won't vote, because sadly Americans are not as committed as they should be to voting. Because the GQP is committed to making voting as hard as possible, a lot of people who vote on election day won't take time out of their schedule, or inconvenience themselves to vote if it won't count. People are also very much about backing a winner, so if you are convinced your guy will lose, you won't waste your time.
