Why the GOP won't fix the country

They never have:

After reading the book, I don’t believe that Ike was a commie, however I believe that if I had been a Commie in the US in ’52 or ’56 that I probably would have voted Ike. Or as Welch puts it: "In April, 1957, Norman Thomas, six-time candidate for President of the United States on the Socialist ticket, stated that ‘the United States is making greater strides toward socialism under Eisenhower than even under Roosevelt.’"

There's a lot on Ike here, most of which is very unsavory.  The GOP has been a bunch of lying hypocrites for two thirds of a century.  What would make anyone believe they will change today?
