Reason Magazine - The Limits of Anti-Kelo Legislation
Thanks to Mystery Reader for this link to an assessment of the limits on "economic development" justifications for eminent domain that were passed all over the nation in the wake of Kelo decision by the USSC.

Legislators have found many different ways to produce bills that appear to protect property rights without actually doing so. Texas, for example, banned "economic development" takings but continues to permit them under other names, such as "community development." The most common tactic, used in some 16 states' post-Kelo laws, is to allow economic development condemnations to continue under the guise of alleviating "blight." While it may sometimes be desirable to use eminent domain to transform severely dilapidated areas, many states define "blight" so broadly that almost any neighborhood qualifies.
