The Democratic chase for the White House is now just a day away from another milepost.
North Carolina and Indiana hold primaries Tuesday and the two remaining candidates both see the outcome as crucial.
Embattled frontrunner Barack Obama bluntly told an Indiana crowd Sunday, "I need your help." Hillary Clinton told a cheering audience in Fort Wayne, "This is the final push."
Obama hopes that wins Tuesday might stop the bleeding from a difficult campaign stretch.
He's zeroing in on a Clinton threat to "totally obliterate" Iran if it attacked Israel and on her call for a summer "holiday" from the federal gas tax. Obama says the Iran threat amounts to Bush-style "bluster and saber rattling." And he dismisses the gas-tax idea as a gimmick that would just help Big Oil.
Defending her earlier Iran comment, Clinton says she doesn't think Iran would attack Israel, but wants to make the consequences "abundantly clear."
No matter what happens Tuesday, both candidates say they'll press on.
