Newt's financial backer calls it quit?

This shows that his campaign is in real trouble. From Business Insider:

While billionaire casino mogul Sheldon Adelson may have rescued Newt Gingrich’s campaign in its early days, today, he may have just buried it.
Bloomberg News reports that Adelson, who has donated $11 million to Gingrich’s Super PAC, does not plan to send any more money Gingrich’s way. Bloomberg is citing an anonymous source “familiar with their deliberations,” though an Adelson spokesman declined to comment.
The move seems to be weeks in the making. After poor showings by Gingrich in the last several races and the re-resurgence of Rick Santorum, the former House speaker has once again been pushed to the back of the Republican field. And Adelson may be shifting his focus. According to CNN, Adelson met with Mitt Romney in Nevada last week and “assured Romney that he will be behind him 100 percent should he become the nominee.” . . . .
