Reminder: Bernie Sanders isn’t running for president and literally cannot win. Don’t bother writing his name in. It’s literally a wasted vote. The same as voting for your dog or for Mickey Mouse.
Also: don’t photograph your ballot. Many states have laws against this and will void your ballot if you post it online.
Also: you have the right to a secret ballot. If a “poll watcher” legit or fake demands to know who you’re voting for you do not have to tell them and they are violating federal law.
Also: You can’t vote online. There are absentee and early voting methods that require a mailed in ballot (use 2 stamps) but otherwise you do have to actually show up.
Also, you are legally allowed to take time off from work to vote
