Secretary of State Hillary ClintonIn head-to-head match ups in Iowa against Ted Cruz, Jeb Bush, Chris Christie or Rand Paul, Hillary Clinton would be the winner by at least 10 points according to a Quinnipiac Poll released  Thursday. Iowa is important because it’s the first state to have a contest for delegates to the national Democratic and Republican conventions.

The Republican that scores best against Clinton is Paul. As of this month’s poll, she’s running 10 points ahead of him in Iowa at 49 to 39 percent. The others are listed as undecided, wouldn’t vote or wanting someone else.

Clinton polls 13 points ahead of Chris Christie at 48 to 35 percent. In December, Clinton trailed Christie by 5 points, according to Quinnipiac.

In a race between Bush and Clinton, Clinton would win by 14 points and attracts a majority of voters at 51 to 37 percent. In 1992, when Clinton’s husband ran again Bush’s father, Bill Clinton beat George H.W. Bush by less than 6 percent in the national election.

The final match up pitted Clinton against Cruz. In that poll, she won by 16 points at 51 to 35 percent. In a December poll, she was only 7 points ahead of the Texas senator.
