RKBA and fair elections are the two biggest, followed in VERY close order by the rest of our civil rights.
A big "canary in the coal mine" is where we stand on the ability to encrypt our electronic data. We lose that, we lose the right to PRIVATE speech and privacy in general. The wiretapping/Patriot Act abuses now being uncovered are a pointer to huge problems by the very same crowd at the executive branch that just supported DC with an amicus.
That said, the Clinton regime sucked even worse than the present on electronic freedom issues.
Y'all should pay attention to a group called the Electronic Frontier Foundation, basically a geek version of the ACLU except that they have NEVER disrespected the 2A the way the ACLU does.
While we're at this from a geek point of view: watch out for Microsoft. They've put massive lobbying into gov't support for a number of bad practices, while building security back doors for the Fedgov right into their products.
Worse, the entire concept of "security by obscurity" is a verified failure, with MS being the biggest (by FAR) supporter. This has crossed over into electronic voting. The biggest electronic voting system vendor is Microsoft - not directly, but Windows is at the core of all the current crop of crapware masquerading as voting systems...and to preserve that, they're blocking open-source alternatives. Electronic voting to Microsoft is part of their PR war against Linux/*BSD/etc...
