CNN-On a relatively quiet day on the campaign trail, former President Bill Clinton stumped for President Barack Obama at a university in Miami on Tuesday, urging young people to register, then vote come November.
Appearing at Florida International University, Clinton called the election pivotal, saying, "If you sit on the sidelines, you are responsible for the consequences."
"I keep reading that young people are not as sure as they were four years ago that they're going to vote," he said, going on to reference his speech at the Democratic National Convention last week. "I tried to argue down in Charlotte last week that that's a bad mistake, we've got a lot of reasons to vote and we've got a good candidate to vote for, and we need to get out here and do that."
As he did at the DNC, Clinton defended Obama's record on issues such as the economy, federal budget, and health care.
Recognizing that Tuesday was the 11th anniversary of the 9/11 attacks, Clinton spoke about his own experience with the tragedy, plus that of his daughter and wife, who was then a U.S. senator from New York.
The former president said that his remarks were appropriate on Tuesday because the day is "being honored by service projects all over America, by people trying to be good citizens.
"And the most important thing that I can say today, before I get into my remarks on behalf of the president, is you just have 27 days to register to vote in Florida," he continued, adding it would "honor the people who have worn the country's uniform" to "be a good citizen."
"The least we can do is show up and vote," he said. "And when people try to discourage you from voting, which is happening in a lot of these voter changes all over America, it should redouble your determination to vote."
Clinton was also on the offensive against Obama's GOP challenger, Mitt Romney, and Republicans in general. He characterized Republican attacks that Obama had "robbed" funding from Medicare as "peddling that old dog. “
“It's a mangy old dog," Clinton said. "It's not true."
