:-Projects like the one in the OP, spending state money for what is essentially personal propaganda.

:-Talking about establishing a militia, which would in practice probably be loyal to him personally, rather than to the state.

:-The military coup he planned in 1992

:-The allegations by the state-paid Cuban doctors who defected that they were being required to campaign for Chavez - I don't give total credence to these allegations, but I think they're much more likely to be true than not.

:-His claims that he is going to remain in power for 25 years, despite the existing (I suspect toothless) laws on term limits.

:-His use of state powers to broadcast propaganda.

:-His hampering of journalistic freedom

:-His concentration of power in his own hands, and hostility to independent oversight.

:-The form of his dismissal of his opponents - he refers to virtually everyone who opposes him as being "against the people of Venezuela", "representing interests", etc. This attempt to dismiss all criticism as not merely misguided in nature but illegitimate in source worries me.

:-His support and admiration for Cuba & Castro, an out-and-out dicatorship. Ditto for his invitation of the former military dictator (and American legion of merit holder) Jimenez to his inauguration.

:-His attempt to present himself as being on the side of the people, against the rest of the government - this worries me that it may be the first step towards setting aside the rest of the government. The rate at which he shuffles his cabinet worries me for the same reason.

That's far from proof that he's not committed to democracy, but it's enough circumstantial evidence to make me bet against it.
