It is VERY likely that the Unions will win this one in Ohio, as the only people that are Union Members that have jobs left in Ohio are those that work on Government Contracts, work FOR the government, teachers, firemen, and police.
Others, such as Nurses, are Unionized and promoting defeat of the Issue 2, on the basis that people will die due to fewer nurses, teachers are complaining about too much time away from kids due to competency testing and no say in classroom size, etc. Police are using the Joe Biden "more crime" B.S., as they want the padded payrolls in ALL Union jobs to continue.
I'm sorry to say that Issue 2 is probably going to be defeated, and HOPE the Republicans in the Legislature are already prepared with a NEW piece of Legislation, that aims at busting the Union stranglehold on Taxpayers and their funneling money to Democrats from the Taxpayers.
There are VERY FEW yard signs that are FOR Issue 2, and every yard sign that is "VOTE NO on 2" I suspect is a Union Member's yard (teacher, nurse, fireman, or policeman, or other Government Employee who wants the fleecing to continue).
Because we don't want our homes and cars vandalized. It's as simple as that.
The second part is the answer to your first observation. There are very few "Yes" yard signs because people don't want to be targeted by the union thugs. Same thing goes for signs and bumper stickers during the elections.
The police and fire are running despicable ads. In one, a fireman tells you how to keep your house from burning down. First, check the batteries in your smoke detector. Second, I don't recall, but something obvious like don't smoke in bed. Third? Vote NO on issue 2!
There's a cop ad, too. Similar emotional argument.
