A coup by any other name is still a coup.
Morales will be judged well by history, despite his failings in more recent years.
the coup was made by Morales and his refusal to respect the constitution (and the referendum)
People could have shown that they disliked that by not voting for him in the Bolivian election.
Which they did! And the early counts and numbers from independent election observers have shown that Morales would face an opponent in the second round. The later count was rigged (after no results being counted for 24 hours, which is suspicious) so that the difference between Morales and his main opponent exceeds 10% - which is according to the Bolivian electoral law enough for avoiding the second round.
Later votes were from rural areas that overwhelmingly favour morales anyway.
Also morales offered to have another election, but the coup happened nonetheless to benefit the interests of Bolivia.
This is by far less worse than what happened in 2000 that got Bush elected in which he refused a recount.
