They won't have to go underground, but I do think they will have to look for another party because the republican party died tuesday night. It will never ever be the same nor conservative again. The moderates hi-jacked it from within and without. Many saw it coming, but tried to deny it was happening while others burried their heads in the sand.
This move will only dilute the "total conservative votes" during future elections between the "Conservative Party" and the Republican Party and indirectly help the Democrats and leftists maintain their majorities at every political level in both the short-term and in the long-term.
