Yes, I’m sure the Democrats would be just as eager to help Trump get on a ballot if he missed a deadline.... this is why Republicans are the loser party
You are ignorant of the facts.
The Democrats hadn't yet missed the August 7 deadline for notifying Ohio of their nominee. That would have happened only if they'd waited until their Convention to nominate Biden. But they already announced last week that they're just going to formally nominate Biden before the Convention. That was an obvious route to get around the issue. So, the deadline won't be missed and Biden will be on the ballot regardless of whether the GOP changed the law or not.

Do you really think that the stunt the Democrats tried to pull in Colorado helped them politically? The Supreme Court slammed them 9-0, so all they did was look petty while accomplishing nothing. Sure, trying to remove Trump from the Colorado ballot made some of their radical base happy, just as this thing in Ohio made some in Trump's base happy. But to everyone else, it looked like a petty effort to avoid an election.
Just because the Democrats did something stupid is no reason for Republicans to follow suit.
