Walker, who has enjoyed a consistent lead all year in Iowa, dropped to third in the most recent CNN poll. He was backed by just 9 percent of likely caucus participants, below Trump at 22 percent and Carson at 14 percent.
It’s a dramatic fall for a guy who led in a Bloomberg Politics/Des Moines Register Iowa Poll with 17 percent as recently as late May. That was approaching the level of support—roughly 20 percent—that most party insiders agree could win the caucuses in a 17-candidate field.
