Overall, 42% of respondents said they side more with the unions, while 31% took Walker's position. Among those with annual household incomes under $30,000, that split was considerably larger, with 46% supporting the unions, and only 20% supporting Walker. People earning $30,000 to $74,999 per year also backed the unions, 49% to 31%.
Yet among those earning over $75,000 per year, 36% said they backed the unions, while slightly more, 40%, said they stood behind Walker.
Last week, a Gallup poll found the same result, with all income groups except the top bracket opposing the idea of collective bargaining rights.
