The most common argument for why Barack Obama should pick Hillary Clinton as his running mate concentrates on her strength (and his purported weakness) among several demographic groups: older women, white blue-collar workers and Latinos. But a couple of recent national polls reveal that Obama is running extraordinarily strong among the latter group.

As noted by First Read, a recent poll of 800 likely Latino voters in 21 states showed Obama with a dominating 60-23 advantage over John McCain. This comes shortly after a WSJ/NBC survey that found the Democratic presidential candidate with a 62-28 lead among Latino voters. By comparison, four years ago President Bush took 44 percent of this key demographic group.
