I have some questions regarding early (mail-in) elections:

1. Aren't the results of all voting supposed to be secret until the official voting day is over and if so, why are some newspapers and polls projecting results?

2. Do we know if some early voters are engaging in Voter Fraud? In other words, are the addresses of all early voters verifiable as belonging to U.S. Citizens?

3. Are there any safeguards in place against Voter Fraud by mail-in voters?

Can anyone offer some answers or other pertinent information?
