If nothing else we can see what other dumb things McCarthy may have said.
In order for the Representatives to "look like America" they just need to be Americans. But McCarthy wants to suck up to the left so he adopts their viewpoint.
Why didn't he mention that Republicans were the party of all Americans since the 1800s? Or that the Republican party had lead the fight against the racism of the Democratic party?
McCarthy is a jerk, its as simple as that.
