One reason this is occuring is that there is no direct consequence to the legislators.
I suggest adopting two very popular memes to reach this goal - three strikes term limits. A legislator who votes for three different laws which are eventually struck down as unconstitutional shall be removed from office, and unable to serve in the legislature again for at least 25 years. Perhaps first offenders can be offered the opportunity to participate in a diversion program, whereby they're forced to [re]take classes in constitutional law and civics, and if they succesfully complete the program and don't reoffend within one year, the first violation will be ignored. -- Greg Broiles | US crypto export control policy in a nutshell: gbroiles@netbox.com | http://www.io.com/~gbroiles | Export jobs, not crypto.
