For those asking why Vidal is a "crank", the reason is that he is a conspiracy theorist which, like other paranoids, lives in a world of "terrifying significance", in Aldous Huxley's apt phrase. EVERYTHING is proof for him of the evil Bush's secret hand at work.
Voting technology is becoming--gasp!--computerized? (Can you IMAGINE? In 2003?) Can't be simply an update, must be a conspiracy.
The company that got the contract has donated money to the Bush administration? Can't be the usual "scratch my back and I'll scratch yours", must be a conspiracy.
The voting machines are made by a private company which wants to protect its trademarked technology? Can't be simple economic sense, must be a conspiracy.
Well, guys... if you want a private company to design the machine, OF COURSE it would protect its own patents! No company would bother to do the research and create the technology to do so, otherwise. Your other options is to let THE GOVERNMENT design the voting machine that will decide who the next government will be... now what's wrong with THAT picture?
Of course, Vidal has not the TINIEST BIT of evidence of any conspiracy. On the contrary, his "arguments" show that he is:
1). A technological ignoramous, as his sneering assertaion that there cannot be any worthwhile technology to protect in the machine because HE cannot think of one shows.
2). Disrespectful of other people's property: give up your patents! His highness Vidal had spoken and said you are just bluffing!
3). Totally lacking in common sense: such a "conspiracy" would necessarily involve dozens, if not hundreds or thousands, of people, all of whom would have to keep quiet forever, and would create the greatest scandal in US history--let alone put Bush in jail--if anybody blabbed, as they are sure to do within two weeks, at most.
This is not the attitude of somebody who is worth listening to. It is an arrogant, sneering, ignorant rant by someone who just KNOWS the "truth", evidence--and common sense--be damned; he's right, you're wrong, that's that.
This is, in other words, the classical personality of an egomaniacal crank.
