Hillary Clinton strengthened her pitch to recognize the discounted Florida and Michigan primaries Saturday following the collapse of yet another re-do primary proposal.

The pitch potentially lays the groundwork for her to make the case to uncommitted superdelegates that she's the popular vote favorite should she narrow the gap with Barack Obama in the upcoming contests.

"I will ... keep fighting to make sure the votes of the people in Florida and Michigan are counted," Clinton said in Hillsboro, Ore., Saturday. "2.3 million voters turned out."

The New York senator won both primaries in January, but neither candidate campaigned there ahead of the vote and Obama was not even on the ballot in Michigan. The Democratic Party stripped the states of their delegations for holding early primaries in violation of party rules.

"Now some say their votes should be ignored and that the popular vote in Michigan and Florida should just be discounted. Well I have a different view," Clinton said Saturday. "The popular vote in Florida and Michigan has already been counted. It was determined by election results, it was certified by election officials in each state. It's been officially tallied by the secretary of state in each state."

Clinton is arguing anew that those elections were bona fide tests of the candidates' appeal among voters, after Michigan Democrats on Friday formally ditched the latest effort to hold a do-over primary. Florida has done the same, effectively killing chances of holding re-dos of any kind.

The decisions mean that hopes for a resolution to seat the delegates at the August convention mostly rest on the two Democrats' campaigns striking a compromise on how to allocate the delegations. And while Obama's campaign has firmly resisted seating the delegations based on the states' January primaries, Clinton's campaign has pushed to have the states represented at the August Democratic National Convention in Denver.

Democratic National Committee Chairman Howard Dean this week even said he's committed to finding a way to seat both delegations, though it's unclear how that would happen.

With the candidates 134 total delegates apart, Florida and Michigan could tip the race, especially if Clinton carries significant wins in the 10 remaining Democratic contests. It's impossible for either candidate to score enough delegates to clinch the nomination on pledged delegates alone in those contests. So aside from Florida's and Michigan's 313 pledged delegates, the superdelegates -- party officials and insiders not bound to either candidate -- could decide the nomination if both candidates tough out the race to the end in June.

That's where Michigan and Florida come into play again. One of the key considerations superdelegates are expected to make is electability, in this case against presumptive GOP nominee John McCain. Clinton on Saturday hinted that the results in Florida and Michigan make her a popular favorite.

"The question is whether those 2.3 million Democrats will be honored and their delegates seated by the Democratic Party as we move forward to put together the strongest campaign in the fall in order to win. And we cannot afford to give up on Michigan and Florida ... in order to do that," she said.

The Obama campaign has proposed a 50-50 split of both states' delegations, an option Clinton advisers have rejected.

Obama spokesman Bill Burton dismissed Clinton's latest call to recognize Florida and Michigan's results.

"Senator Clinton herself said these contests 'didn't count for anything.' But now that it serves her own political self-interest, she's trying to change the rules and count the results of contests where she and every other candidate pledged not to campaign," Burton said. "In Michigan, Senator Obama wasn't even on the ballot. Our focus should now be on seating the Michigan and Florida delegations in a fair manner."

Saturday was Clinton's first campaign visit to Oregon, whose primary is May 20. The state holds a largely vote-by-mail primary with ballots mailed starting April 28.
