Hoosier State Democrats and Republicans go to the polls Tuesday, with the fate of Ted Cruz and Bernie Sanders hanging in the balance and things not looking entirely promising for either in their respective primary. Josh Robin filed the following report.

Thirteen months campaigning, and Ted Cruz finds himself surrounded by Trump supporters in Marion, Indiana.

"Sir, with all respect, Donald Trump is deceiving you. He is playing you for a chump," Cruz said to one of the supporters.

Whatever he's doing, Trump is handily ahead in the latest Hoosier State poll, to say nothing of the delegate count.

"Indiana is very important because if I win, that's the end of it, and otherwise, we have to wait until the following week, and we'll see," Trump said. "I think Indiana is going to be great. We are having such popularity here."

Popularity amid anti-Trump protests across the country.

Counting on Trump's unfavorability rating, nearly double his favorables, Cruz is vowing to continue on. Amid dwindling odds, he wants a contested national convention in Cleveland.

"Now ask yourself. Do you really want to go through the next four years with a president who, if your child came home and simply uttered the words coming out of that president's mouth, would make you punish your child?" Cruz said.

On the Democratic side, Bernie Sanders is also hoping the Democrats don't pick their nominee before they meet in Philadelphia in July, but that's even more remote than for the GOP.

The Vermont senator couples it with a plan you could also call fanciful. Superdelegates - the party insiders overwhelmingly backing Hillary Clinton - should take a look at polls and defect his way.

"You know what those polls show? They show that, by far, Bernie Sanders is the strongest candidate to defeat Donald Trump," Sanders said.

Sanders is also calling Clinton's fundraising "money laundering," showing no signs of giving up so far. He also is far behind in the delegate count after a bruising New York loss last month and then losing four out of the last five primary contests.

Clinton is turning to the general election, appearing in Kentucky, which holds its Democratic primary later this month. She's predicting a new role for a former president on the economy.

"We have to have a partnership. I told my husband he's got to come out of retirement and be in charge of this because, you know, he's got more ideas a minute that anybody I know," Hillary Clinton said.
