Does IRV mean moving to DRE voting machines?
Absolutely not. No jurisdiction in the U.S. has switched to DRE machines as a result of adopting IRV, or even considered it. Nearly all IRV elections are conducted using optical scan paper ballots. The key national organization promoting IRV, FairVote, advocates against the use of DRE machines, and favors the heightened security and election integrity provided by optical scan ballots using both paper ballots and a redundant computer record.
