Donald Trump and Ted Cruz are in a virtual tie in Iowa with its caucuses less than a week away. A Quinnipiac University poll released Tuesday has the pair in a dead heat, with the businessman leading the Texas senator by 2 percent — but the survey has a margin of error of almost 4 points.
The poll surveyed likely Iowa Republican caucus participants. One thing does seem clear: Iowa is a two-man race.
The next closest Republican candidate is Sen. Marco Rubio with 15 percent of the vote; that's still 14 percent behind Cruz.

The survey found Trump gets more support than Cruz from those who describe themselves as somewhat conservative to liberal. Cruz bests Trump among self-described evangelicals, tea party members and the "very conservative."
