Relative to much larger drop in the overall popular vote though.
It goes without saying, if the two party system is to be preserved, the GOP will either break into Hispanics, or break into a great share of the White Working Class vote and change accordingly to achieve that end. The current GOP may not get above 60%, but is that any different from saying that the current GOP cannot get over 35% amongst Hispanics?
Well,
In order to be more appealing to the latinos: they would have to moderate on social issues (immigration).
In order to be more appealing to the whites: they would have to moderate on economic issues.
The first scenario is more likely.
