McGrath, could you tell us something about UK elections?
Mechanical, electronic or paper ballot? If one of the former, is there a method of checking the ballots? Are systems uniform throughout the UK? (They vary from state to state here).

I know election costs in the U. S. are high. Probably close to $6.00 a voter for primaries but higher in general elections but this is just a guess.
The Florida Attorney General estimates some 20 million to hold a Primary re-vote. About 3.4 million voted in both primaries there. If the $20 million cost is correct, that comes out at about $6.00 per voter.
In general elections, all sorts of things to vote on are added at the local and state level, from bond authorizations to changing rules to authorizing a bounty on stray pussycats.
