The Telegraph article seems to be the chief source for the various articles that turn up on Google under "bulldozing cities" or "bulldozing neighborhoods."  I think the RW is seizing this as a meme and trying to use it to bash Obama.  It seems to have originated from a local official in Flint, Michigan, who saw it as a path to solvency for Flint and sought help from first the Obama campaign and then the Obama Administration.

Next we may have Obama's black bulldozers coming to a neighborhood near you.  No doubt Rush will soon pick up on this.
