New York City Mayor Michael Bloomberg is officially ruling out a 2008 presidential run and is pleading the next president to take an independent approach to governing the country.

In an op-ed today he specifically asked the candidates to adopt independent positions on trade, jobs, immigration, education, global warming and gun control.

Bloomberg writes: "I believe that an independent approach to these issues is essential to governing our nation — and that an independent can win the presidency. I listened carefully to those who encouraged me to run, but I am not — and will not be — a candidate for president. I have watched this campaign unfold, and I am hopeful that the current campaigns can rise to the challenge by offering truly independent leadership. The most productive role that I can serve is to push them forward, by using the means at my disposal to promote a real and honest debate."
