All the ETH under the from-address will be counted as corresponding ballots.
For the transactions to be done successfully, a minimum amount of transaction fee of 0.0006 ETH is required.
If your wallet (for instance, Mist) does not support 0-ETH transactions, a minimal amount (e.g. 0.0001 ETH) is recommended. The smart contract will send back any amount of ETH it receives automatically.
The status is an on-going real-time counting.
