Where did the Republicans go?

I became a Republican in 1980 much to chagrin of my grandmother an avowed FDR Democrat. My views have not changed not much - but when I look up I am standing mostly alone. The Republican party somehow moved right when I was otherwise distracted with life. Now the party is a parody of itself. The parties are a side show to distract and obscure attention from the real party in power, the Incumbent Party.
