Democrat election experts are trying to get the word out on the extent Trump is going to trying to steal the midterms.
Don't assume your vote by mail will be counted they're doing everything they can to block it. instead vote in person at the polling station. Before you vote make sure you are still registered, Republicans are going after voter rolls for a reason they intend to remove people from the rolls and hope they don't know or don't bother to register again.
So check in advance, if you get to the polls and are NOT allowed to vote, demand a provisional ballot and cast it. if your actual vote is somehow blocked the provisional ballot SHOULD allow you to vote.
They're also suggesting Dems may need to organize ride pools to get people to the polls who don't have a way of getting there. Apparently the law requires you to have 2 people in the vehicle if you do this and then passengers
They also STRONGLY recommend you make sure you know in advance where your voting location is, REpublicans are doing all sorts of shenanigans closing polling places or moving them around so people show up at the plac they've voted for 20 years and it's not their polling place anymore.
The key point they're stressing don't give up, they're doing everything they can to stop Dems from voting they want us to just give up,
