Sen. Steve Kaiser has introduced legislation that could make him a hero of Arizona motorists -- assuming it gets approved and survives a likely court challenge. The Phoenix Republican wants to ban political signs from street corners, medians and other public rights of way.

In a case with nationwide implications, the U.S. Supreme Court this morning ruled the Town of Gilbert illegally blocked a tiny church from erecting temporary signs directing parishioners to services.

A small church in a Phoenix suburb appeared likely Monday to win its Supreme Court dispute over a local ordinance that puts limits on roadside signs that direct people to Sunday services.

The town of Gilbert is asking the U.S. Supreme Court to quash a bid by a tiny religious congregation to be able to post and leave up year round its signs directing people to its worship services. But the case is about more than a spat between one community and a pastor. There are statewide and national implications on the ability of communities to enact restrictions on certain kinds of signs. And the stakes are so high that even the Obama administration has weighed in on the side of the church, asking the justices to void the town's restrictions.
