A couple of months ago, Scott Walker was the new big thing among the Republican hopefuls -- at least in Iowa. He was the choice of 24% of Iowa Republican voters (14 points higher than any other Republican). Now his support has been nearly cut in half -- resting at 13% (3 points less than Bush, and only 1 point better than Rubio).
What happened? Has the new worn off, or are the possible legal problems of Walker starting to affect his candidacy? I'm not sure, but Walker's return to the pack means their is no real leader in Iowa right now.
Christie and Santorum have also lost a significant amount of support among Iowa Republicans -- while Bush, Rubio, and Carson have gained significant support. All of the other candidates are basically where they were in February.
These numbers are from surveys done by Gravis Marketing on February 13th and April 13th (with both dates having a 5 point margin of error).
