Clinton touts popular vote lead

Hillary Clinton didn't get all the delegates she wanted out of the Democratic National Committee's ruling on Florida and Michigan.

But she is trying to make the most of the popular votes she added, claiming that she's now ahead of Barack Obama on that unofficial count.

In a new TV ad that will start airing Monday in Montana and South Dakota -- which hold the final primaries on Tuesday -- she urges voters to "join over 17 million people who’ve voted for a leader to fix the economy….for a commander-in-chief to bring our troops home from Iraq...17 million who want to beat John McCain."

"Seventeen million Americans have voted for Hillary Clinton...more than for any primary candidate in history," the announcer says. "Some say there isn’t a single reason for Hillary to be the Democratic nominee. They’re right. There are over 17 million of them."

Obama, however, leads in the official delegate count and appears likely to surpass the number needed to clinch the nomination on Tuesday night.
