Problem is, unless polling's way off, the only viable majority will be Con+SNP, which isn't going to happen. My guess is the polls are optimistic from Labour's standpoint and we'll see a 50+ Con majority, with the Lib Dems basically wiped out (signally the end of them as anything other than a rounding error). In the unlikely scenario we get a minority Tory government, it wouldn't surprise me if we go through all this shit again by the end of the year.
