Fit in Socially Liberal Enablers of the Democommies No thanxIf one were to consider the current USA political/ideology spectrum as a circular "pie", the Democrat Party (DNC) has shifted so far to the extreme Left in the past 50+ years as to exclude many whom would have been "Democrats" "back then". It's highly doubtful that either FDR or JFK would gather $upport and endorsement from current DNC were those 'political persons' here today.
The Democrats/DNC fill a slightly less than one quarter "slice of the pie" so to speak. That means that as the only other viable and major political party in the USA, the Republicans (RNC) have their quarter slice of the pie in form of stanch Conservatives and the other half(two quarters plus) of the "pie"; the "others", whom can only be considered RINO/CINO*, would have to be in the assorted "third parties" which have little resources or membership to be viable contenders, or squeeze into the GOP somehow.
RINO/CINO is essentially just those whom aren't "Radical Leftist" enough to get $upport and backing from the extreme socialist/communist Democrat Party, nor strongly Conservative enough to be considered "real" Republicans.
Since RINO/CINO are near automatically rejected by the Democrats, their only place for acceptance would/could be in the Republican tent, which is more expansive and encompassing.
Many of us in the GOP aren't trying to get rid of the "RINOs(CINOs)" but rather trying to find ways to fit them in.
* RINO/CINO = Republican In Name Only/Conservative In Name Only.
