>Given that senior citizens make up 12-14% of the total population and have the highest turnout of any actual voting demographic (72% actually cast a ballot), it's unlikely. :o) More than 82% of seniors registered to vote in the last election.

>OK, but people under 20 make up 27% of the population and are likely to have 45 tax-paying and voting years before them. ;-) Traditionally they may not vote consistently but if society turns into a tyrannical Gerontocracy, that may change. ;-)

It wasn't until 1971 that 18-20 year olds could vote (26th Amendment). Initially they had a strong showing. However, that was due to Vietnam. Figure the odds that a majority of 18-20 year olds will vote in the next presidential election! :o) Most figures track youth 18-24 or 18-29. Regardless, the majority of youth voters vote Democrat and Democrats typically vote for more social programs so it still wouldn't happen. :o)
