Wisconsin Gov. Scott Walker announced on Monday he is joining the crowded 2016 Republican presidential field of nominees.

"America needs new, fresh leadership with big, bold ideas from outside of Washington to actually get things done," Walker says in the 89-second video announcing his run. "In Wisconsin, we didn't nibble around the edges. We enacted big, bold reforms that took power out of the hands of the big government special interests and gave it to the hard-working taxpayers — and people's lives are better because of it."

Walker will become the 15th Republican candidate when he officially launches his campaign from Waukesha, Wis., later Monday.

"We fought and won. In the Republican field, there are some who are good fighters, but they haven't won those battles. And there are others who've won elections, but haven't consistently taken on the big fights. We showed you can do both. Now, I am running for president to fight and win for the American people. Without sacrificing our principles, we won three elections in four years in a blue state. We did it by leading. Now, we need to do the same thing for America," Walker says in the video.

He also tweeted his announcement.

 

 

In a RealClearPolitics average of polls, Walker is polling second to former Florida Gov. Jeb Bush with 10.5 percent to Bush's 16.3 percent.

Walker, 47, was elected governor of Wisconsin in 2010. He also defeated an effort to recall him in 2012. In mid-June, he announced he was forming a "testing the waters" federal campaign committee to decide if he wanted to run for president. He announced on July 2 he would announce his candidacy on July 13.
