In 2008, John McCain won 55% of white non Hispanic votes.

In 2004, George W. Bush won 58% of white non Hispanic votes.

The common wisdom seems to be that the Republicans must court Hispanic voters in order to remain politically viable.

Why?

Although whites will one day be in the minority in the U.S. (though far and away the largest minority) that isn't slated to happen until the 2040--2050 time frame.

There are a lot of elections between now and then. If the Republicans can increase their percentage of the white vote to 70% or more, then they can win the next four or five presidential elections with very little support from minorities.

After gaining power, the Republicans can then pursue some kind of outreach to minorities.

But why do the Republicans want to waste time and effort getting a point or two of Hispanic and black votes when they could start a determined pursuit of white voters from a position of strength.?
