Rep. Joseph Cao (R-La.) will stump for Virginia gubernatorial nominee Bob McDonnell (R) tomorrow at a Vietnamese shopping center in Northern Virginia. Cao, who knocked off ethically-challenge Bill Jefferson in 2008 in Louisiana's heavily Democratic 2nd District, is the first Vietnamese-American ever elected to Congress.

In the Nov. 3 election, McDonnell is hoping to unsettle the mostly Democratic dominance in Northern Virginia, where nearly one-third of the state's voters reside.

Cao will join McDonnell at the Eden Center in Falls Church, one of the most ethnically-diverse locales in the state. Gov. Tim Kaine (D) campaigned alongside Deeds Oct. 17 at the Eden Center, home to a number of Vietnamese-owned small businesses and restaurants.
