“Latinos ’08” (9 p.m., PBS): Who will Latinos support at the ballot box next

“Latinos ’08” (9 p.m., PBS): Who will Latinos support at the ballot box next month, and what impact will they have on the outcome? A new documentary, “Latinos ’08,” explores these voters, who are less cohesive than many other voter blocs plus less likely to conform to the simple black-white categorization that has long shaped American politics. Will John McCain manage to win back Latino defectors after the Republican Party’s harsh rhetoric on immigration? Will Barack Obama land the votes of the many Latinos who supported his fellow Democrat, Hillary Rodham Clinton, during the primaries? The 2008 election will likely serve as an important indicator of the future direction of Latino politics. Among those heard from in the film are Henry Cisneros, secretary of Housing and Urban Development for the Clinton administration; columnist Ruben Navarrette Jr.; and political commentator Leslie Sanchez.

“Dirty Sexy Money” (10 p.m., ABC): Things are getting hot, hot, hot on “Dirty Sexy Money,” where the wacky Darlings find themselves dealing with the aftermath of a major fire, a death in the family and a surprising arrest connected to the demise of Dutch.

“The Sarah Silverman Program” (10:30 p.m., Comedy Central): She’s cute, obnoxious and depraved: That’s the honed-to-perfection persona of Sarah Silverman in her standup comedy and, more recently, on her Comedy Central sitcom. Now “The Sarah Silverman Program” is returning with new flights of freewheeling wrongness by her character (also called Sarah Silverman), a whimsical, self-consumed slacker. In what’s being billed as a two-night premiere event, new episodes air Wednesday and Thursday at 10:30 p.m. On Wednesday, Sarah gets high for the first time, and keeps track of her ideas and plans by leaving voicemail for herself on her cell phone — a ready reminder to misguide her. On Thursday, she finds out her Russian ancestors were raped by Mongolians. Concluding that even after 800 years the statute of limitations hasn’t run out, she sues the entire nation of Mongolia. Living her obliviously misspent life in the town of Valley Village, she is looked after by her sister (played by Silverman’s real-life sister Laura), her gay-couple neighbors (Brian Posehn and Steve Agee) and Laura’s dimwitted policeman beau (Jay Johnston). Rounding out the support system: Doug, a Chihuahua-pug mix played by Duck, Silverman’s real-life pooch — and, oddly, the show’s only character with a made-up name. Somehow, that figures.
