Should The Republicans and Conservatives Court to Minorities for Votes?

I mean knowing that in the year 2050 white Americans will be the minority while the majority will be Hispanics, Blacks, Asians, and immigrants Legal and Illegal with the majority being Hispanic overwhelmingly. I mean the Republican party really sucks with minorites, Mcain got obliterated by Obama in the 2008 election because of the Hispanic vote in states that are normally red like Florida,North Carolina, Virginia?? Nevada, and Colorado. Even with this, Republicans still keep bashing immigrants which is going to come up and bite them in the a-s-s!!!! for example the governor of Arizona who passes anti-immigrant laws, and Romney saying "they should go back to wherever they came from" this only fuels the Democrats. Even George Bush said the same thing in his last press conference before he left office, he said that one thing he would change about his party their stance on immigrants and courting of minorities because minorities do not want to vote Republican because of ridicoulous rants from Republicans "Republicans donot like immigrants, so they must not like me either" W. said it himself!!!! Whats going on here???? Come on Republicans you guys are going to ceaze to exist by the year 2050 if you guys dont change your policies. What do you guys think
