Mayor of New York, Michael Bloomberg, has an op-ed in the Times that appears to be an announcement to run independently for president.  Of the current candidates, he says,

They must know we can’t fix our economy and create jobs by isolating America from global trade. They must know that we can’t fix our immigration problems with border security alone. They must know that we can’t fix our schools without holding teachers, principals and parents accountable for results. They must know that fighting global warming is not a costless challenge. And they must know that we can’t keep illegal guns out of the hands of criminals unless we crack down on the black market for them.

And just when this gets good, just when you think Bloomberg can steal everyone’s partisan thunder: 

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.

Still, this thing is cryptic, and I wouldn’t be surprised if this wasn’t his bid to be the next vice president.
