Scott Walker Makes It Official: 'I'm Running for President'

He's the 15th Republican to join the race.

— -- Scott Walker made it official today, jumping into the race for the White House as the 15th declared Republican candidate.

“After a great deal of thought and a whole lot of prayer, we are so honored to have you join with us today as we announce that I am officially running to serve as your President of the United States of America,” the two-term Wisconsin governor told a packed house gathered at the Waukesha County Expo Center in Wisconsin for his formal announcement event -- the same place where he declared victory following a recall election in 2012 and sealed his rise to national acclaim as the only governor in U.S. history ever to withstand a recall.

Walker, 47, joins a crowded field or Republican competitors but already assumes frontrunner status in the important first-in-the-nation contest state of Iowa, where he has led every major poll since February following a breakout speech at the Iowa Freedom Summit in January.

The most recent Quinnipiac University poll showed Walker polling a solid 8 points ahead of his closest competitors with 18 percent of likely Republican caucus-goers favoring Walker.

If elected, Walker would be the first president since Harry Truman -- elected over 70 years ago -- not to have a college degree.

Walker would go on to make his first bid for public office at age 22, a race he lost. But three years later, in 1993, Walker won a seat in the Wisconsin state legislature and hasn't lost an election since. He went on to become the Milwaukee County Executive in 2003, and in 2010, was elected governor.

Walker’s formal announcement Monday night came after he first broke the news of his candidacy in a Facebook post early Monday morning.

“I'm in. I'm running for President of the United States because Americans deserve a leader who will fight and win for them," the two-term Wisconsin governor says in the Facebook post, which includes a video in which he argues that his track record as governor sets him apart from the rest of the Republican field as a proven leader who has succeeded in winning elections and taking on big policy battles.
