What would make more of a picture would be to check the percentage voting before a company switched from plurality to what the percentage was when that proxy proposal to switch to Majority was included in the following proxy of the same company.

As an example when BAC switched from plurality top majority in 2006...this was their heading on the proxy to their shareholders...their words not mine...

From BAC proxy notification in 2006

"Why your vote matters

Many individual shareholders do not vote their proxies because they feel that their vote will not have any impact on the outcome of vote totals. We believe all shareholders should exercise their vote and tell management and the board of directors of ALL companies they own – through their vote - how they feel about their board and management’s performance. "

And Neal Gerber and Eisenberg LLP did a survey regarding such a switch to majority voting whether it be a by-law change or simply a change in company policy (which is what they seem to perfer) they had positve reaction to the switch too...the last paragraph esp.

But whatever your opinion of voter apathy is I'll take majority vote over plurality any day.

It certainly can't be any worse than "1 vote and your elected" proxy voting
