A Bloomberg Politics article reports that Senator Ted Cruz's "hard-charging style troubles general election voters. In the Bloomberg Politics/Des Moines Register Iowa Poll earlier this month, Cruz performed worst among potential Republican presidential contenders in a hypothetical matchup with presumed Democratic frontrunner Hillary Clinton."
That's not accurate. Secretary Clinton polled 45% against Cruz, but 46% against Jeb Bush, so by that measure, Governor Bush did "worst." And in any case, the Bloomberg Politics article does not mention that the poll has a margin of sampling error of plus or minus 3.1 percentage points. Statistically, the 35% that Mr. Cruz polled against Hillary Clinton is a tie with Jeb Bush's 39%, Chris Christie's 38%, Marco Rubio's 37%, and Rand Paul's 41% (add plus 3 to Mr. Cruz's 35 percent and subtract minus three from Mr. Paul's 41%, and they are tied at 38%.)
I emailed the Bloomberg reporter to ask him about his use of statistics to label Senator Cruz as worst and will update this post if I hear back.
