Former Pennsylvania senator, Rick Santorum has cancelled a trip to Iowa after being hospitalized over the weekend.

The 2012 Iowa Caucus winner was due to return to the state Monday to attend two metro events but according to a spokesperson, “became ill and was admitted to the hospital for a gastro-intestinal illness and dehydration.”

The Former Republican presidential candidate was due to be the keynote speaker for the spring fundraiser for the Iowa Faith & Freedom Coalition in Urbandale and to also attend the John Paul II Medical Research Institute for a stem cell research event in Des Moines.

His condition was improving Sunday, “He is feeling better today but remains in the hospital,” Virginia Davis, a spokesperson for Santorum’s political action committee Patriot Voices, said. “He is expected to resume a full schedule later this week and looks forward to returning to Iowa soon.”

Iowa Republicans have been trying to figure out what to do after disappointing elections in 2012. 2008 Iowa Caucus winner Mike Huckabee warned them not to give up on their principle beliefs.

Huckabee spoke in Des Moines Saturday night to about 250 people at the Republican Party of Iowa’s “Celebrate Life” event. Huckabee urged Republicans to stay true on opposing abortion. He said, “It’s important for people to realize that the Republican Party values the dignity and worth of every human being.” Huckabee continued, “Every life has value. And so the message of pro-life is not just about abortion, it’s about celebrating every life as having great value being a gift from God with a special purpose.”

Scientists are coming to a consensus that man-made acceleration of climate change is real, the issue also got a mention in the President’s State of the Union Address after being absent from the Presidential debates.

Now, Iowans across the state want action on the issue.

Residents will deliver letters to Congressional offices in at least 10 cities on Friday from Fort Dodge to Council Bluffs.
