Trusted Leadership PAC to spend $1.6 million to hit Kasich in the Hoosier State.

Washington (CNN) It wasn't just a Wisconsin thing.

The main super PAC backing Ted Cruz is reprising its attacks on John Kasich in Indiana, which is shaping up to be a major battleground in the Republican race ahead of its May 3 primary. Trusted Leadership PAC on Friday said they would spend $1.6 million to hit Kasich in the Hoosier State.

After channeling most of their attention on front-runner Donald Trump, the same group also decided to hit Kasich hard in Wisconsin ahead of its primary earlier this month.

The advertisement airing in Indiana once again features President Barack Obama praising the Ohio governor for expanding Medicaid, which is anathema to the GOP's conservative base. A version of the ad also aired before the New York primary.

"John Kasich cannot beat Hillary Clinton because he is too much like her on core issues - like Obamacare. Voters deserve to know this," Kellyanne Conway, a super PAC adviser, said in a statement.

Senator Cruz is the only candidate that fits those qualifications."
