The actual issue here...
is not whether or not one kind of light bulb is a good idea compared to the other. The issue is exactly where some politicians think the limits are as to how much control they have over our lives. For all that I hear about "right-wing authoritarianism," it's almost exclusively Democrats that believe that our every waking moment should be overseen and patrolled by our loving overlords in the seats of government.
Someone who thinks it's acceptable to make light bulbs illegal (imagine the smuggling issue) will have few other limits in how they think the State should run your life for you.
Believe me, this particular legislative stinker is just one of many. This one just happened to hit the papers.
