SALENA ZITO: Centuries later, Scots-Irish attract political courters.

When national campaign strategists consider targeting an ethnic voting bloc to swing results in their direction, they typically consider blacks or Hispanics.

Yet, an ethnic group they often overlook — the Scots-Irish — are the voters the Republican Party persuaded in 2010 to swing back to GOP candidates, after they swung toward the Democratic Party in 2006, experts say.

As the 2012 election approaches and both parties eye the White House and U.S. House and Senate seats, strategists from both parties say the Scots-Irish again could be critical to winning.
