It is not a circular firing squad, it is Conservatives (real ones), it is the American People, firing at the stupid Repulican/Democrat oligarchy. If you can't see what is going on today, I feel sorry for you.
A lot depends on the definition of "conservatives, real ones." Reagan is the only one that qualifies in my lifetime.
And he did several things, which instantly earn "rino" labels today. The definition of "conservative" has changed, and fewer people want to be called Republicans.
The largest "party" is now Independents. That is who to appeal to, if one wants to win elections.
I'm interested in winning elections. My district is represented by a conservative Republican, who has chosen to not identify as a member of the Tea Party. The political makeup of the district is trending towards the democrats, each election cycle. The racial demographics are changing, too.
Ignoring all that, pushes one evermore towards the irrelevant and out-of-touch side. I'm not all "hair on fire," every day.
I'm in favor of unity, and opposed to the constant "schism."
