Would it or could it work in Hamilton County? Who wants it to happen? In Indianapolis the Dems are now pushing for it, but the Republicans started it.
There have been calls for it locally by certain Republicans. I think their motive is power, not cost savings. Excluding the right leaning people fleeing to the far out burbs, most people in the county are Republicans, so any elections would produce a GOP controlled city government. Would anything good come from that? Well, if you want a right wing social agenda pushed on you, then you might just want it. As a form of government, uni-gov for the county makes great sense. In practice I fear the bigotry of the fundamentalists with money (CCV) controlling the legislature.
