Michael's post on how to adapt the 50-state strategy for the Ontario NDP is definitely worth a read.

But let's highlight as well what may be the most important lesson to be taken from the Dean/Obama experience. The time and money put into reaching every corner of the province (or indeed the country at the federal level) shouldn't be seen purely as a cost: instead, investment in uncharted territory tends to pay off in terms of reaching potential supporters and donors who can ultimately expand the pool of resources available to help in the obvious priority ridings as well.
