Last night, the California Senate debate had both candidates up in arms — literally. Congresswoman Loretta Sanchez rounded out her final statement by dabbing at the end.

Sanchez's dab was immediately all over social media, but there seemed to be little about the actual debate.

According to a recent Los Angeles Times/USC Dornsife poll, roughly one quarter of California residents are undecided on which candidate they will vote for this November.

So, who are these candidates? Sanchez and Attorney General Kamala Harris are both Democratic candidates for Barbara Boxer's seat in the U.S. Senate. Although both candidates are Democrats and second-generation immigrants, the two have differing views.

Sanchez has served as a U.S. Congresswoman in the House of Representatives for 19 years. Sanchez focuses heavily on immigration reform, homeland security, human trafficking and surveillance. Sanchez urged Gov. Jerry Brown to sign Assembly Bill 2888, which would require prison time for people found guilty of sexually assaulting someone who was unconscious or too intoxicated to consent. Sanchez also opposes Proposition 57, which would allow non-violent criminal offenders a chance at parole.

As in any campaign, Sanchez has faced criticism. Harris criticized Sanchez for her attendance record in House of Representatives. In the debate, Sanchez claimed that 20 percent of Muslims want to form a caliphate to target Western norms. The California Immigrant Policy Center disagreed with her, saying her figures were "wildly off-the-mark."

Sanchez currently trails in the polls by more than a 2 to 1 margin.

Harris is also a Democratic woman of color. Harris started as a Deputy District Attorney for Alameda County and worked her way up to District Attorney of California. Harris emphasizes higher education, immigration reform, civil rights and criminal justice reform. She boasts endorsements from President Barack Obama and Vice President Joe Biden.

Harris has been very vocal about advocating for free community college and public university education for families earning less than $140,000 per year.

Sanchez has claimed Harris is naive when it comes to Washington affairs, and has accused her of being too silent in the conversation of police shootings. Sanchez flashed figures during the debate showing that during Harris' time as attorney general, statewide violent crime and homicide rates increased 10 percent last year.
