It's almost guaranteed. The liberal Boomer control over political decisions is already diminishing, and with the exposure of and clamp-down on voter fraud in the next few years it will become more painfully obvious to big government proponents of both parties.
The younger working Americans are getting squeezed from every direction due to the policies enacted by people who are either already retired or nearing retirement. Over-taxation from every level of government, over-regulation, bloated bureaucracies, open borders, off-shoring of entire industries, etc., etc., -- this squeezing will force the younger eligible voters to get politically active at earlier ages than if the elders had planned responsibly for the nation's future.
Boomers will see electorial defeats starting in 2008, and by 2012 their grey-voter issues will be completely trampled into the mud. I expect we'll see means testing for social security, wealth taxation on the retired, lower taxation on the productive working citizens, more tightly controlled borders and immigration, dismantling of EPA, ESA, medicare/medicaid, social services at all levels, total dismantling of tax-exempt status for dot.org type outfits of all kinds, including churches. It won't be done for revenge; it will be necessary for the survival of the nation.
For the record, I am also of the Boomer generation, but I am objective enough to see that the political decisions driven by the votes and demands of the Boomers since the early 1970's have created grave threats to the future economy and culture of the United States. Gen-X and Gen-Y voters will have enough numbers in 2008, and moreso in subsequent election cycles, to reverse some of the damage.
Since 1970 we have had 25 years under a republican P and 12 years under a dem P. Theres a lot of good and bad like everything else.
