Washington (AP) Hillary Rodham Clinton says people will have to decide the democratic presidential nominee first, but she's hinted at a ticket with Barack Obama.

During a series of morning talk show appearances, Clinton said a shared ticket “may be where this is headed” once a nominee is determined.

She says Ohioans clearly think she should be the top choice.

Clinton told NBC'S “today” show voters are starting to ask “hard questions” about Obama.

Obama also made the TV rounds, playing down primary losses to Clinton in the battleground states of Texas and Ohio. Obama's take is that he still leads in the all-important delegate count.

Both democrats predict they will win their party's nomination and say they have the credentials to go head to head with republican nominee-in-waiting John McCain.
