Many of us are concerned about touch-screen voting systems that are vulnerable to tampering and cannot be double-checked.
If you share these concerns, you may want to write to your Representative and ask him or her to support the bill introduced by Rep. Rush Holt (H.R. 2239) to require all computer touch-screen voting machines to include an auditable paper trail. It doesn’t necessarily solve the tampering problem, or the freezing problem, but it’s a lot better than nothing.
