One thing I'm seeing regarding the bridge tolls is a disturbing number of transplanted New Orleanians who voted for them due to some version of, "Where I'm from we have tolls so that's probably the non-backward thing to do."
Aside from the bullcrap about mowing the grass and threatening to let the bridge fall into the river, I can't think of a less-informed or more irrelevant reason to have supported the tolls but it's a popular one among the transplants I talk to. I guess the best way to poll this demographic regarding the tolls would be to propose it on Neighborland and letting the kids there tell you what they think.
Since we're down to counting absentee ballots now, it will be interesting to see if the voters who were transplanted away from New Orleans have a better sense of this thing than the ones who were transplanted to it.
