"If we can win Iowa," Trump quipped, noting that it's the only state where his closest competitor is within striking distance, "we can run the table."
"We may not lose a state because it is going to feed."
Trump spoke in Norwalk, Iowa, on the morning after his endorsement by Tea Party favorite and 2008 GOP vice presidential nominee Sarah Palin, a move seen as a coup for him and a blow to Ted CruzRafael (Ted) Edward CruzFiorina: Biden picking Harris for VP 'a smart choice' Russian news agency pushed video of Portland protestors burning a Bible: report After trillions in tax cuts for the rich, Republicans refuse to help struggling Americans MORE, Trump's closest rival. Palin didn't appear with Trump on Wednesday morning but is expected to campaign with him in Tulsa in the afternoon. 
Trump regained first place in Iowa polling on Jan. 14, one month after Cruz knocked him out of the lead. The real estate magnate now holds a 1 percentage point lead in Iowa over Cruz, according to a RealClearPolitics average of recent polling. 
He spent a significant chunk of his rally bashing Cruz — calling him two-faced while questioning his eligibility to serve as president as well as his defense of not disclosing loans he took around his 2012 Senate campaign. Cruz-bashing has become a recent fixture of Trump rallies after the two butted heads over Trump's challenges to his eligibility because of his birth in Canada. 
"He said with being a Canadian citizen: 'Oh I didn’t know that.' How did he not know that? He said with the loans: 'Oh I didn’t know that,' Trump said of Cruz. 
"Smart guy? He didn’t know that. That’s worse than Hillary," he said in reference to her controversy surrounding her use of a private email server while secretary of State.
"He takes ads and says things about me that are so wrong, so we have to disclose the real facts,” Trump added. 
Trump also rubbed in the Palin endorsement and Iowa Republican Gov. Terry Branstad's call to Iowans Tuesday not to vote for the Texas senator, saying it would be "damaging to our state." 
"That was a big statement to come out with yesterday — yesterday was a W, you had that statement and you had Sarah Palin," Trump noted.
"That was a good day for Trump."
