Texas Sen. Ted Cruz is staring down today's Indiana primaries,

, Associated Press reported.

Donald Trump shows a commanding lead in a recent poll of likely voters in the state. Like Ohio Gov. John Kasich, Cruz is already mathematically eliminated from reaching the delegate majority before the Republican National Convention in July.

A Cruz-win in Indiana could lead to a contested convention.

If he loses Indiana, it would be Cruz's seventh consecutive primary loss.

The anti-Trump movement's only hope is to deny the billionaire businessman a 1,237-delegate majority by defeating him in Indiana and the handful of contests remaining over the next month. Then that candidate would have to beat Trump when delegates gather in Cleveland in July.

Cruz hinted at an exit strategy yesterday, even as he vowed to compete to the end against Trump.

"I am in for the distance -- as long as we have a viable path to victory," Cruz told reporters after campaigning at a popular breakfast stop.

Last week, Cruz announced failed presidential candidate Carly Fiorina as his running mate.

He also announced an alliance with Kasich to stop Trump, a strategy that may have backfired. An NBC poll found nearly 6 in 10 Indiana primary voters disapproved of the alliance.

Should Cruz and Kasich throw in the towel if Trump wins Indiana?
