How about a new thread on the Iowa caucuses? The off-year caucuses in 2014 could be extremely important on the Republican side. The U.S. Senate nomination could be decided at a statewide GOP convention, if no candidate wins at least 35 percent of the vote in the June primary. Furthermore, supporters of Governor Terry Branstad will need to focus on electing delegates at the precinct, county, and district levels, if rumors of an attempt to replace Lieutenant Governor Kim Reynolds on the ticket are accurate.

Democrats in the first Congressional district have extra incentive to turn out supporters for the 2014 caucuses as well, in case none of the five declared candidates in IA-01 wins at least 35 percent of the vote in the primary.

As for the next presidential-year caucuses, U.S. Senator Amy Klobuchar of Minnesota was the featured speaker at the north Iowa Democrats’ “Wing Ding” event in Clear Lake last Friday. She indicated that she is not interested in running for president and even joked that Minnesota supplies the country with vice presidents. If Hillary Clinton does not run for president again, Klobuchar is one of several Democratic senators who might join the race.

Former U.S. Senator Scott Brown of Massachusetts visited the Iowa State Fair on Sunday with his wife, Iowa native Gail Huff. He wants to know if there is substantial support for his “brand of leadership and Republicanism.” I can hardly imagine a worse fit than Brown for Iowa Republican caucus-goers.

Speaking of which, Governor Chris Christie of New Jersey signed a bill banning so-called gay conversion therapy for minors in his state. That intrusion on parental decision-making will be a deal-breaker for social conservatives.

Senator Ted Cruz of Texas, the new darling of the Iowa Republican base, has released his birth certificate to show that he is eligible to run for president. He will also renounce his dual Canadian citizenship.

Governor Scott Walker of Wisconsin, my early pick to win the 2016 Iowa caucuses, previewed his future case against GOP members of Congress who may become rivals for the presidential nomination.
