At his first solo rally of the 2012 election campaign, former President Bill Clinton tonight invoked the 9/11 anniversary to urge all Americans to register to vote and endorse President Obama’s vision for a future of “shared prosperity.”

He also took shots at Republicans and GOP presidential nominee Mitt Romney, whom he said were conspiring to discourage Democratic voters and would take the country on a drastically different path.

“I decided to come here on this day because I think if you look around at how this day is being honored today — it’s being honored by service projects all over America, by people trying to be good citizens,” Clinton told the crowd of mostly college students at Florida International University.

“The most important thing I can say today … [is] if you want to honor the people who’ve worn the country’s uniform … be a good citizen,” he said. “The least we can do is show up and vote.”

Clinton called Obama’s race against Romney a “pivotal election” with high stakes for the middle class and the poor.

“I believe we should be working, in an interdependent world, for an America of  shared responsibility, shared opportunity, shared prosperity and shared membership in one American community. That’s what I believe in,” Clinton said.

He said the opposing approach was a “a militant, bitter, anti-government strategy,” though he did not mention the Republican candidate by name.
