Mayor Rahm Emanuel is standing by Hillary Clinton in her quest to be elected president. But after her upset by Sen. Bernie Sanders in the Michigan primary, he is hinting that Clinton needs to retune and focus her message somewhat.

The mayor today also had some sharp words for developer Bill Davies, who is complaining that the city is messing up his pending deal to sell the Old Main Post Office. Emanuel's message: Too bad.

At a midday news conference, Emanuel shrugged off Clinton's loss in Michigan, a diverse, racially mixed state in which she was thought to have a big advantage over Sanders

"She won Mississippi," which also held its primary yesterday, Emanuel said. "She's won a lot of other states. Campaigns are not about one state. She will be the (Democratic) nominee. She has a strong economic message."

But Emanuel, who was a senior aide to Hillary Clinton's husband, Bill, when he was president and endorsed her in the 2016 race many months ago, did seem to suggest that her economic message has not resonated

"Over the last 12 to 18 years, the American people (on average) have not had a raise," Emanuel said. "Their income has been stagnant."

What the country needs is both an improved economy and jobs, Emanuel said. The Michigan outcome was about "jobs and economic" concerns.

The Old Post Office came up when Emanuel was asked about a statement released by Davies' company that a deal to sell the historic but hulking structure to an unnamed New York investor is near, but endangered by the city's move to acquire it via eminent domain.

The building has been empty for two decades, and Davies' International Property Developers has owned it since 2009, Emanuel said.

"The time to act is now. The time is up. We've given him plenty of time."

That sounds pretty clear to me.
