Democrats say Trump, GOP are intimidating voters in 4 states

In each lawsuit, the state's Democratic party is seeking court action to preemptively block potential voter harassment or intimidation from Republican poll watchers or other observers.

In a federal lawsuit filed in Cleveland, the Ohio Democratic Party accused Trump and Republicans of conspiring to threaten, intimidate and prevent minority voters from casting ballots in the perennial battleground state.

[...] it is partnering with another group called Vote Protectors to conduct exit polls and plans to compare those responses with the voting machine results in 7,000 precincts nationwide.

The lawsuit there said the state Republican Party is essentially an arm of Trump's campaign and the campaign and its backers have been organizing "citizen journalists" and "poll watchers" to flood minority-heavy polling sites on Nov. 8.
