Sorry if this has been brought up before, but has there been much discussion about what Scottish independence would mean for the Labor Party in Westminster, if they lost a huge base of support and seats due to losing Scotland?
It has, and the answer is that Scotland has too few seats to make a difference except in the most close elections. It won't lead to eternal Torie dominance forever. The real Labour base is Northern England, so unless Manchester and Liverpool suddenly want to become independent, left-wing Englishmen have nothing to fear.
In difference to what Jerry said , it's not really like losing the entire West coast. Scotland doesn't even hold 10% of the UK population...
Sure it'll make it harder, but not that much harder.
