DES MOINES – Both the Republican Party of Iowa and the Iowa Democratic Party received substantial growth in their ranks during the past 75 days, much of which is directly attributable to the Iowa Caucuses. Iowa Democrats increased by 27,451. Iowa Republicans increased their ranks by 26,095.

"It's very exciting to see so many Iowans engaged in the political process," Secretary Pate said. "Clearly, these statistics show that Iowans care deeply about the direction and future of our country. They want to make their voices heard. I encourage every eligible Iowan to get involved in elections on every level, from the school board all the way to the White House."

Many Iowans registered to vote or changed their party affiliation at their Caucus locations. County auditors across the state received thousands of voter registration forms from the parties after the Iowa Caucuses. They had 45 days to process those.
