You can find the original question (which included Romney) and the results here.
Before we say the poll is flawed, consider that only 3 or 4 percent say that Ted Cruz would be their choice. Even if the real figure were double or triple that, it falls short of what most of us would expect. Of course the campaign hasn't even really started and he'll do better if he runs, but isn't this a reality check?
Maybe it's the circles we move in online and the people we talk to on the Internet that aren't representative of typical Republican voters, the 47% of the population that voted Republican last time, or the 50% that would have to go that way again for the GOP to win.
