> It's clear based on what the government is doing now that the liberal democrats firmly kept them in check and gave us a few years of much better governance.
I'll agree so far as saying that Conservative/LibDem governance produces better policies than solely Conservative governance (as least as far as civil liberties etc. are concerned), but I'm unconvinced it was the right move to make.
Firstly, it may have enabled them to keep the Conservatives in check to some degree, but, by providing an effective government majority, it may have resulted in some of the Conservative proposals passing at all, rather than being rejected in the House of Commons if the Conservatives formed a minority government.
Secondly, I suspect that the LibDem support of the Conservatives, and the years of stable government that followed, may have contributed to Conservative gains in future elections (the Conservatives being the senior party, it is easier for them to claim the credit, deserved or otherwise).
> As to the second part, this often stated thing about the pledge on tuition fees - they were the junior partner in a coalition - expecting them to somehow be able to uphold all their policies in that situation is insane.
Again, I'll agree so far as them to uphold all of their policies in coalition is something that could never happen, but the pledge on tuition fees was rather different from the traditional manifesto pledges. It was signed by individual candidates/MPs, rather than as a party, and stated:
"I pledge to vote against any increase in fees in the next parliament and to pressure the government to introduce a fairer alternative"
Expecting MPs to follow through on something so plainly stated, and importantly something that is not contingent on the LibDems being in government, is not unreasonable IMO. It should have been obvious that reneging on that pledge would cause a huge loss of trust in the LibDems, regardless of what they were able to achieve in government, especially in a year when one of their election broadcasts was titled "Say goodbye to broken promises".
