Poor Shrubby,
When you get to be as old as I am, you will see that whenever a political party is on the skids, it will be back and on top in about 2 to 3 years. This has happened to the Republicans, I have also seen it with the Democrats. So, no, the GOP will not shrink to obsolescence.
As for minorities, the only reason they think I or whites in general hate them is because people like you have been telling them that since birth.
I see you have no problem hating people who want to do nothing to you.
