I want to point out that it was Suthep and the PDRC which thwarted the electoral process, not the military.
I'm not sure it's very productive to think of those as two distinct entities - almost the first announcement of the junta was 'reform before election'. At the lower levels, the military provided muscle for the mob (it was, for example, widely reported that armed Navy personnel were working in the PDRC camp) and at the higher levels, well, there are fairly persistent rumours of other connections.
The military watched what was going on to see if an election could be held through the processes inherent in the existing legal structure and I think it is clear that Suthep and the PDRC were willing and able to continue to frustrate the electoral process and the gov't was not able to stop Suthep and the PDRC and successfully carry out an election.
If the army had wanted the election to go ahead, it would have gone ahead. There can be no doubt about that. In fact, had the elites (including the army) allowed it, the police alone could quite easily have ensured the election was a success.
Certainly, the fact that Suthep, the Democrat Party, the independent agencies, the courts, the senate and the military have in turn conspired to overthrow a democracy and replace it with a military dictatorship means that right now, Thailand is not a democracy. Nobody is going to argue about that. But that doesn't mean that prior to the coup, Thailand was not a democracy. It was certainly at far from the best health imaginable, but as I've already said, that doesn't mean it wasn't a democracy.

A meaningful transition to political stability will require a re-appraisal of the central role of the monarchy, a new culture of respect for electoral and parliamentary institutions, and the development of a modern opposition party that can provide the Thai electorate with real policy alternatives.
That seems to me like a fair summary. How we get there from here, I don't know.
