Polls say Ted Cruz is gaining in Iowa, where two new ones show him reaching second place with around 20 percent of the vote.
But the same polls suggest he has a big challenge: He has very little support outside of a growing base of self-described “very conservative” voters.
“Very conservative” voters can propel Mr. Cruz to victory in Iowa, a caucus state, but according to exit poll data from 2008 and 2012, those types of voters represent a smaller share of the electorate in every primary state. CONT.
