DAVENPORT, Iowa – A lot of people are talking about Donald Trump, but Scott Walker is determined not to be one of them.

The Wisconsin governor, kicking off a three-day tour of Iowa, continued to parry questions about the billionaire New York developer’s strident anti-illegal immigration rhetoric, which has propelled Mr. Trump to the top of the 2016 Republican presidential polls. While attention-starved lower-tier candidates like Rick Perry and Lindsey Graham – along with former Florida Gov. Jeb Bush, who is making a concerted appeal to Hispanic voters — have condemned Mr. Trump’s remarks, Mr. Walker affirmed Friday that he won’t take the bait.
