An Arizona diarist at Daily Kos points out how critical
veto power is. The point is well-taken, especially in states with legislatures as reactionary as Arizona's.
The Arizona Democratic Party (note: partisan source, treat it accordingly) has
a list of some of the bills that Arizona's Janet Napolitano has vetoed. It's quite an amazing list. And it's a healthy reminder that the veto can be a very useful tool in the hands of a savvy executive.
