Nicole Wallace summed it up well...
After Donald Trump’s acceptance speech at the Republican National Convention last week, Nicolle Wallace, a longtime GOP strategist, had a memorable exchange with NBC’s Chuck Todd.
WALLACE: [T]he Republican Party that I worked for for two decades died in this room tonight. We are now represented as a Party by a man who believes in protectionism, isolationism, and nativism. And those were the forces that George W. Bush, and I believe John McCain too, were most worried about during their times as the leaders of the Republican Party.
CHUCK TODD: Striking comment. You believe the party died tonight?
WALLACE: Well, the voters picked this guy. This is where the Republican Party is now. They now are attracted to those forces of isolationism and protectionism. But the party I was part of for two decades is dead.
