Diversifying the GOP isn't just good PR: it may be necessary for the party's national viability. The Republican base has gotten whiter and whiter, but whites are shrinking as a percentage of the overall electorate...

Who would have thought that states like Virginia and North Carolina would be swing states for a Black democrat in 2012?

Eventually, probably not in 2016 but perhaps by 2020 and definitely by 2024, given current demographic and voting trends, a state like Texas will become a swing state. That would be the death knell for the current version of the Republican Party winning a national election. Like it or not the country is changing. The Republican Party has to win a respectable proportion of the Hispanic-American vote to win the Presidency. This will be even more urgent as the Hispanic-American population grows and moves to "red" states.

Unless there is a seismic shift of white liberals and moderates to the Republican Party over the next few elections, the Republican Party will not be able to run on its current messages and win.

In my view both parties are just different wings of the same system but the Republican Party since Goldwater and Nixon has made a bargain with some very reactionary elements of the country. But those groups are declining in numbers. The Party will have to adapt and change, just as Clinton did for the Democrats in 92. It's better for both parties and the country if neither party can take voters for granted or write off their votes.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
