Not just "back" under permanent Republican rule, but apparently also "back" in time.. Most conservatives who dream of overthrowing the government believe the country lost its way some time in the past. Some point toward the 60s, the time of the counter culture, the civil rights movement, and their perceived war on Christianity. Others point toward the 30s, when we had the New Deal and sweeping government changes.
They see themselves as the victims. Government has been out of control since one of those two decades. They believe Presidents Clinton and Obama are blatantly violating and ignoring the Constitution, as is the so-called activist Supreme Court. Apparently Reagan and the Bush family were stalwarts of liberty, and I guess the Supreme Court is only an activist court when it rules against the interests of the cancer that is conservatism.
One interesting thing is that in the conversations about taking the country "back" that I've witnessed, nobody ever proposes to fire the first shot. They always believe their dream will turn into reality once the government uses the police and/or military to move against American citizens on a widespread basis. General gun confiscation or having conservatives declared as domestic terrorists and then thrown into jail or reeducation camps seem to be the most popular theories.
There was also Jade Helm, which started two months ago, and which some conservatives thought would finally be the beginning of their dream, but apparently someone forgot to tell President Obama that he is supposed to order the Special Forces training in Texas that their real mission is to put the entire state under martial law
