That's exactly what it is "a guess" and a pretty dumb one at that. My advice is to learn a little more about political philosophy before you feel entitled to speak on behalf of what others may have been thinking.

"The National Commission on Federal Election Reform, which he co-chaired with President Ford before his passing, found and argued that voters should always vote alone and in secret, a right and a degree of ballot integrity that is impossible to protect with NRAV."

This quote seems to suggest that AV voting should be eliminated period. For example, in 2005 Jackie Curry, the former Detroit City Clerk, was rumored to have visited several nursing homes where she "helped" a number of elderly and incapacitated people vote AV. The current extension of AV voting would have little if any effect on exacerbating a pre-existing problem enabling under the current exemptions for AV voting. To be fair, the lines to vote in Detroit are notorious for being significantly longer than those in the suburbs. And even I believe this an unequity that should be remedied. However, the AV process is not neccessarily the best way to remedy this problem.
