Scott Walker a possible running mate to Ted Cruz? He says, "I don't know what the future holds"

MILWAUKEE -- Gov. Scott Walker may hit the road to stump for Ted Cruz, a major stepping up of his involvement in the presidential campaign. This, as Cruz and John Kasich team up trying to defeat Donald Trump.

Walker helped Cruz win Wisconsin on April 5th. Now, he says he may campaign for Cruz in Indiana.

"Apparently they have some interest. We'll have to see schedule-wise if it's going to work or not," Walker said.

It would fuel speculation that Walker is on Cruz's short list of possible running mates. In West Allis on Monday, Gov. Walker did not rule it out.

"I don't know what the future holds. I can just tell you, I love being governor. My focus is on being governor," Walker said.

Indiana voters head to the polls on May 3rd -- and it is critical for Cruz. He and John Kasich have struck a deal. Kasich has cleared the path for Cruz and Donald Trump to go head-to-head in Indiana.

"I've never told them not to vote for me. They ought to vote for me, but I'm not over there campaigning and spending resources," Kasich said.

Cruz is leaving Oregon and New Mexico to Kasich.

"We had conversations -- and both campaigns agreed to focus our energies," Cruz said.

Donald Trump called the move "pathetic."

"Did you see the news today? Did you see? Where they band together, where they collude. You know, it's collusion," Trump said.

Gov. Walker says he did not suggest the alliance. But he does think it is a good strategy to defeat Trump.

"I think they should've talked amongst candidates sooner," Walker said. "I think there are better choices out there. If a majority of the voters get behind those choices, not only will my party be better, the country will be better with a better choice."

Trump will campaign with former Indiana basketball coach Bob Knight this week.

Meanwhile, Walker predicts Trump will not have enough delegates before July -- and it will be a contested convention in Cleveland.
