Obviously my policies are varied, so I'll have to choose a few to discuss.
1) Nothing Good Happens After 2:30 am Act of 2006 After several years of debate in my lower House of Consciousness and a some flip-flopping, this policy went into effect five years ago, to great effect. The Organized Activities Commission's subcommittee, The Committee For Staying Up and Late Drinking, received sweeping new powers to enforce curfews, and impose temporary budgetary freezes. So far, it has kept me out of several fights, prevented me from being in the middle of other people's drama, and ensured that my Sat / Sun mornings aren't ruined by exhaustion. I'd say this policy has been a rousing success in my life and led to few, if any, situations where I regretted calling it a night at 2 am.
2) The Girlfriend Act of 2008 In reality, The Girlfriend Act was a reform package which reformed policies that had been in place under the Temporarily Single After Having My Heart Broken Act of 2006/2007, which had, of course, been proceeded by the She Could Be The One Declaration of 2005. It brought sweeping changes to my Budget Office, Organized Activities Commission, my Bureau of Fermented, Distilled, and Brewed Beverages Office, My Foreign Policy Office (including the Penis Deployment Office, whose complicated filing system was shelved), and it had a dramatic effect on my Executive Office, with the installation of a new Vice President. It also had a temporarily dramatic effect on The Budget and Social Outlook Foresight Committee.
While these reforms were highly effective for a long time, they lost their edge recently. In early October, polls had indicated that the Happiness Factor was down nearly 75%, and the comprehensive report compiled by the Budget and Social Outlook Foresight Committee was grim. The house and Congress last week rushed through a dramatic overhaul under the Now Single Act of October 2010 which has boosted employment and reinvigorated many sectors of my economy which had been stagnant.
So, while The Girlfriend Act pulled me out of a recession, brought prosperity and joy to my life, and helped determine my long-term outlook, it was time for it to go. I'd give it a "moderately effective" rating.
3) Finally, we should probably examine the Deployment to Canada Act of 2007 and the subsequent Move in With High School Friends reform bill of 2008. The former, while well-conceived, was highly debated for many months. On the Pro side, we had impassioned speeches about being able to live abroad, spend time with family, make new friends, etc. the Con side pointed out how far away it was, how unsure I was about the employment I had accepted, and how I knew only a few people there. Ultimately, of course, the Pro side won and, while it was a great adventure filled with a few good times, it has to be seen as an ultimate failure in light of the Move in With High School Friends Act which brought much rejoicing. It has been in effect for two years and probably will not change for at least another year or two.
Those are the only policies I've ever been responsible for and, as you can tell, they've been a mixed bag, though mostly with positive results.
