Just so the results of voting can be displayed on TV a bit earlier, we are supposed to accept substantial risks to democracy posed by blatantly insecure endpoints, blatantly insecure company infrastructure, insecure network communications and devices (routers, etc.), private companies that often have a track record of insecure and sloppy programming, voting machines that have been shown to be hackable easily (people from CCC and similar groups do that routinely when they get hold of a machine), voting program code that has been improperly audited and/or cannot be verified by the public, flawed patching mechanisms, flawed and insecure operating systems of voting machines, and on and so forth. The list of flaws of electronic voting systems is nearly endless, and, what's worse, there is no mathematical proof that the encryption used in those systems cannot be broken. (There are lots of proofs in cryptography, but almost all of them are based on very strong idealizing assumptions. In the end, only OTPs are provably secure. We do not even have a proof that P!=NP yet.)
