Cameron's Shameless Embrace Of Kahn Smacks of Desperation

Do I sense a slight bit of desperation in David Cameron's warm embrace of Sadiq Khan in opposing Britain's exit from the EU? Only a couple of weeks ago, Cameron and his Conservatives were smearing Labour candidate Khan, attempting to link him to Muslim extremists, in his winning campaign to become Mayor of London.  Now, Cameron is calling Khan a "proud Muslim, a proud Brit, and a proud Londoner" because Khan also opposes Britain's exit from the EU. Yes, this is simply typical of all shameless politicians, but I think in this case it speaks to a real fear that the country will vote to leave the EU, which would mean the end of Cameron's political career.
