Margaret Ritchie set out her strong preference for the Labour Party as the SDLP's southern bestest friend. Right said some, wrong said others (this blog included).
But in purely practical terms, the fit is hard to see. The map below, taken from the NUIM Geography's Eye on the World blog (and cited in today's Irish Times) shows that the Labour Party in the south is, well, definitely in the south. It is weakest precisely at the points closest to the SDLP heartlands of Derry and South Down. In fact, it is almost nonexistent in all of the constituencies around the border.
This means that if Ritchie expects her new friends to canvass for her she might get a surprise. Because they simply aren't close enough to do so. Very few are going to come from Kildare, let alone Cork, to help out. The constituencies within an easy commute of the SDLP's target constituencies have virtually no Labour presence and thus no hands and feet to offer.
More evidence of Ritchie's poor judgement?
