A quick postscript to the week in American politics which you might have thought was over.

Michael Bloomberg might (although we’ll see) be getting into the Democratic race. It’s not yet confirmed and reality might not align itself to whatever preconditions the former New York mayor has set himself for his participation, but the fact that he’s not allowed the closing date for entry into the Alabama Democratic primary to pass without filing his papers suggests that he’s still out there, even if at the moment that means only keeping a watching brief.
