Madison— Scott Walker has made busting up unions a signature element of his campaign. But what if the issue itself is something of a bust?

On Monday, the Wisconsin governor debuted his latest plan to curb union power, only to see it draw scant notice from the media and next to nothing from his rivals for the Republican presidential nomination.

Walker hoped the plan could help drive the 2016 discussion back to him, but in the three-hour GOP debate Wednesday, the proposal never came up. Walker didn’t even have much of a chance to mention it himself.

The governor is finding himself in a race that’s turning, at least for now, more on issues such as the terrorist threat from the Islamic State and President Barack Obama’s nuclear agreement with Iran.

“If (the proposal) got attention, I missed it,” said Stephen Roberts, a former chairman of the Iowa Republican Party and Republican National Committee member from Iowa. “I don’t think it’s one of the things that people down here are focused on.”
