You can easily implement e-voting without letting anyone prove that they voted a certain way. This leads to concerns about rigged elections, but those same concerns are present with traditional voting. At the other extreme, you may be able to construct a crypto-system where someone can prove that there vote was incorrectly counted without being able to prove how they voted. The downside to this approach is that it is likely that would likely involve a fair amount of technical knowledge to verify that the "receipt" you get from voting corresponds to the vote you intended to case. A middle ground would be to allow people to detect when their vote is mis-counted, but be unable to prove it. This can be easily accomplished by giving every voter a random ID at the time of voting, and then publicly posting the ID/Vote pairs.
