Actually it means both republicans and democrats.
Well that's what the liberal establishment keeps telling us, but it's just cover and they know it.
The Republicans are NOT in power.
They can't stop anything Obama does. I do believe it's anti-Rino but that doesn't make it anti-Republican anymore than it did in 1980 when people were fed up with the Republican establisment and voted in Reagan.
People might remember the establishment wanted Ford (in 76) and then Bush the elder in 1980.
The voters wanted Reagan. That's anti-establishment, not anti-Republican.
There isn't a Reagan on the Democrat side. There isn't anything close.
It's anti-Democrat, because they ARE the ruling class in Washington right now, and they don't have an alternative.
