The percentage of non-Hispanic whites voting for Republican House candidates in 2010, 62%, set a record for off-year contests, beating even the 1994 Republican rout when Republicans got 58% of the white vote

In presidential elections, you have to go back to the landslide Republican victories of 1972 (Richard Nixon versus George McGovern) and 1984 (Ronald Reagan versus Walter Mondale) to get white Republican margins similar to those of 2010. McGovern and Mondale carried just one state each, Massachusetts and Minnesota respectively. Another way of looking at it is this: fully 88.8% of all ballots cast in 2010 for House Republicans were cast by whites, compared to 63.9% for Democrats. This is why the Republicans should stop wasting their time pandering to the Hispanic population. Republicans win elections when they maximize their white voter base.
