Greg Scandlen recommends that Americans who want to get involved and help move this country in the right direction do so by helping their state-level free market think tank.
For example, Colorado has the Independence Institute. Their Health Care Policy Center is run by Linda Gorman, and I've been a long-time friend of Brian Schwartz who runs their health policy blog PatientPower.
Their Second Amendment Project is run by David Kopel, who has written extensively about gun rights.
Overall, I like much of what the Independence Institute does and I'm glad they are here in Colorado.
One way to find similar organizations in your state is through directory listing of the State Policy Network (search by state in the pull down menu.) Of course, you should do your due diligence to ensure that your state/regional think tank supports your values. But if they do, Scandlen notes that you can help by contributing money as well as expertise.
The states are going to be key battlegrounds in the fight for American freedom. There's never been a better time to jump into the fray!
