Whenever anyone said "It's time we gave the Liberals/Lib Dems a chance", I had a stock reply. "Yes, let them show us how 'realistic' they'll be in power. Let them stick their noses in the trough."

Before the election (six weeks ago?) the Liberal-Democrats were bent on scrapping Trident. Now they want to keep it.
Before the election the Liberal-Democrats were going to get rid of university tuition fees. Now not only are they going to keep them, they're going to raise them.
Before the election Vince Cable was going to introduce strict regulation of the market and stop bankers' superbonuses. After the election Vince addressed a cluster of fatcats and told them that, when it comes to the city, he's a deep-blue tory.
Before the election Nick Clegg was sick of Israel's treatment of the Palestinian people and intended to do something about it if he won office. What he's done since becoming deputy prime minister is declare his undying love for Israel. On British subservience to the USA, which he deplored before rising in the world, he has yet to pronounce. I predict a change of heart.
