The order is here. It is broad and important, including stopping Roger Stone’s group from purported to engage in “exit polling” that is really about questioning and hassling voters.
It doesn’t apply to the Ohio Republican Party, I assume because there is no evidence that the ORP, unlike the Trump campaign or Roger Stone, has engaged in any activity that has threatened voters or claimed a massive problem of voter fraud.
BUT, why does the order also apply to “groups associated with the Clinton for Presidency campaign?” Is this an effort to be “even-handed?” There’s certainly no evidence that I’ve seen anywhere of the Clinton campaign raising vote fraud or threatening to harass voters at the polling place. Very odd.
