Despite Westly's momentum and resources, the California Democratic Party endorsed Angelides at the State Democratic Party Convention. The race turned extremely negative, highlighting environmental controversies surrounding Angelides' background as a real estate developer and Westly's broken pledge to keep his campaign clean. Westly's candidacy also was hurt by an unprecedented multi-million dollar independent expenditure by Sacramento real estate developer and longtime Angelides patron Angelo Tsakopoulos. As election day neared, Westly's momentum dissipated and the race tightened. A Field Poll held on June 2, 2006 had Westly leading Angelides by one percentage point, 35% to 34% with 26% undecided and an error size of +/- 4.5 points.
