The problem is in the "leadership" and not among the Republican people, the majority of whom are conservatives.
Hope that helps clear things up for you.
My 90% RINO number was based on Federal elected offices.
As for RNC leadership, 100% of them are RINOs. To wit: They control who they support through donations. We’ve had true conservatives run for gov. in NJ in the past 15 years, but neither the state or national GOP supported them via ads or money. They did not win.
Which takes me back to a vatiation of my original question: Why would Demrat Party controlled RINOs step aside for conservatives?
