It doesn't work very well,
whatever uppity backbenchers claim, because the first - past - the - post system means most people aren't represented by someone they backed.
It scrambles up and onward always by spiralling round
whatever stands in its path — drainpipe, porch pillar, / lawn chair — but then, once anchored, corkscrews round itself, amassing braided cables of self - hugging self - satisfaction, the conquering hero's doublejointed pat on his own back, the unbridled ego trip impelled by the
uppity sap from deepest root to farthest outflung tip, ecstatically, imperially quivering toward its vegetal entelechy.
