In the final week before the Iowa caucuses, Ted Cruz’s campaign has quietly shifted its TV attack ads from hitting Donald Trump to hitting Marco Rubio, sparking speculation that he's worried about a late surge by his Florida colleague.

But the final Bloomberg Politics/Des Moines Register Iowa Poll shows that Cruz isn’t in danger of being overtaken by the Florida senator. Rubio rose from 12 percent in early January to 15 percent among likely Republican caucus-goers, but the poll also found that he dipped by a few points over the four days that it was conducted. Cruz was in second place with 23 percent, while Trump led with 28 percent.
