With a newly redrawn district where Democrats and Republicans are split evenly and with 20% Independents, OC County Supervisor Janet Nguyen has a favorable demographics to win the seat from the term-out Lou Correa (D).
The California Republican Party is pulling out all the supports for her. She is leading her opponents in money raised so far. Also, the district is heavily populated by Vietnamese-Americans. Thus, their expected high turn-out will give her a strong voting base. Of course, it is only 2013 but the conventional wisdom is that she will be formidable as she continues to rally the party base and reach out to indepedend voters.
