Gov. John Kasich says he and other supporters will keep working to persuade voters to keep an Ohio law that limits the bargaining rights of 350,000 public workers, while a new poll suggests that's going to be hard work. With just two weeks before the vote, the Quinnipiac University poll found that 57% of registered voters want to repeal the law, while 32% want to keep it. The poll has a margin of error of plus or minus 2.4%. Kasich says he is undeterred. "We're going to keep working. We think this is the right thing to create an environment for cities to be able to be successful; we're giving them the tools," he said. Supporters will make their case again Tuesday night, when a debate on Issue 2 - the ballot question on the collective bargaining law - airs on 89-7 FM and NBC affiliates statewide. The event begins at 7 p.m. The Quinnipiac University poll surveyed 1,668 registered voters by phone last week. The percentage of respondents opposing the law has almost doubled since a Sept. 27 Quinnipiac poll. The most recent poll found GOP voters more supportive of union limits, 59% to 32%. However, majorities of Ohioans in numerous other categories don't want the law, according to the poll. They include both men and women, whites and blacks, those making more than $100,000 and those making less, and both those with and without college degrees. Kasich said the poll - which also showed a widening margin of disapproval with the job he's doing - will not get him down.    "Do I seem disheartened? I mean, I'm doing my job," he said. "You do your job, you put your best stuff forward, and you live by the outcome." He said it has been a campaign of emotion versus facts, and cited "a lot of misinformation" in prompting voters to oppose the bill.
