I use these sites to see what races are on my local ballot and to get an idea about who is running. If you need more info, you might search on some of your local news stations or newspaper websites.
For the major races, like President or Congress, hopefully you have already decided by now.
There are a few communities on there which I still check, but I spend a significantly less amount of time on Reddit than I used to. I also refuse to post anything or interact on that site anymore.
