There is little doubt that corruption exists in our electoral system. There is no nation wide standard of ballots, or ballot counting, with each state having jurisdiction over the process. Furthermore, with the politically correct laws enacted in the past few years to make it easier for the so-called "disenfranchised" to vote, fraud can run rampant.
Where I live, in Oregon, we have "vote by mail." In many locations there is no ID or proof of residency required, so there is much fraud that takes place here. For those who do not have faith in the mail, or for the "last minute" voters, each county sets up "ballot drop off" sites. The largest county, Multnomah (Portland), can always be counted on to make a last minute surge for the Democrat candidates. For some reason, theirs is always the last county to release their vote totals.
There is ample anecdotal evidence of literally bus loads of homeless, SEIU / ACORN folks, students and illegal aliens moving from ballot drop off site to ballot drop off site within the county. Somehow, Republicans never seem to be able to win in the Portland and Eugene (largest population regions) areas. Granted, Portland is well known as a bastion of liberal activism with socialist elected officials calling the shots. I know there are a few Conservatives living there, but they don't seem to count for much. They are the truly disenfranchised voters. The only Republican, or conservative candidates who manage to win, are in the local races in rural and other out-lying areas. By law, the state Attorney General can not investigate fraud on their own. In what is known as a complaint driven system, they can only investigate after the election and only on specific complaints. Of course, the complaints are always found to be not valid.
The state legislature is now in the process of considering vote by phone, and vote by Internet laws. I'm certain such a system would be even more corrupt than our present one.
I got this at Portland city hall. They are very proud of their reputation.
