This is a good thing. The GOP needs to run a Presidential Candidate who is closer to the political center. This is good for the USA. The choice between a moderate Democrat and a 'fire and brimstone' Republican too many in the electorate is no choice.
Whether this move can or will happen is another question.
Also, if the GOP moves a little left will they lose their 'pro-life', NRA, "small-government", "rape is really a good thing", immigrants are bad for the US...one issue voters?
If so will losing these voters hurt them in the Electoral College just as much as only have the white male demographic?
