You likely cannot vote online today in the United States. In federal elections there is no online voting; you must vote in person at an official polling place or use an approved absentee method if eligible. If you’re voting in a state or local election, online voting is generally not available and you’d typically vote in person or by mail/absentee, depending on your location and the specific election rules. If you share your country, state, or locality, I can provide precise guidance on how to vote today and any urgent steps to take.
