Although everyone's attention at the Democratic National Convention tonight is, naturally, focused on former president Bill Clinton, two other speakers should get the party base fired up.

Women's rights activist Sandra Fluke and Massachusetts Senate candidate Elizabeth Warren will have their moments in the convention spotlight.

Fluke made headlines earlier this year when she testified before Congress that birth control should be covered by health insurance.

But she became embroiled in a national controversy when firebrand conservative commentator Rush Limbaugh suggested Fluke was a "slut" and a "prostitute" for essentially saying that "she must be paid to have sex." He later apologized, an apology Fluke rejected.

Warren may be lesser-known among the general public, but she's a political gadfly for the Republican faithful. The left-leaning Democrat is attempting to unseat Senator Scott Brown, who won the seat left vacant by Ted Kennedy's death.

To help in that endeavour, convention officials are giving Warren a primetime spot and the key role of introducing Clinton.

Warren became a bit of a YouTube sensation over comments she made last year in which she defended against charges that the Democrats were waging "class warfare" against the rich.

"There is nobody in this country who got rich on his own. Nobody."

Sound familiar? Those words are very similar to comments President Barack Obama made in July in the now-controversial "You didn't build that" speech.

Although Democrats have repeatedly said Republicans are taking the president's comments out of context, it will be interesting to see if either Fluke or Warren repeats that theme.
