This is how it’s gonna happen;
Hung parliament, Lib-Dems side with Labour (just) and Gordon Brown remains PM, but with a mixed cabinet – Vince Cable becomes chancellor for example.
Conservatives lost their last chance, Cameron remains leader, but sees the polls turning against him… loses the next election (after the 2010 one) and loses leadership…tory party comdemned….lib-dems replace them as second party….
That’s what’s gonna happen.
