Wisconsin Governor Scott Walker is one of the two remaining holdouts on the Republican side who have yet to declare a candidacy. The other is Ohio Governor John Kasich, who recently set July 21 as his announcement date. Reports indicate that Walker will announce his 2016 presidential campaign on July 13 near his hometown in Wisconsin.

Report from Bloomberg:

Wisconsin Governor Scott Walker will announce his presidential campaign intentions on the afternoon of July 13 in suburban Milwaukee, a Walker aide who wasn’t authorized to speak on the record said.

The two-term governor will make his announcement in Waukesha, just west of his home in Wauwatosa, Wisconsin. The date of the announcement was reported earlier Thursday by Politico.

Walker, 47, is also expected on Thursday to file his papers of candidacy with the Federal Election Commission, the aide said.

If he formally enters the race as expected, he would be the 15th Republican to do so. The most recent public polling in Iowa shows him atop the field in the state that will host the first nomination voting in February, although his standing has slipped this year as others have officially joined the contest.

Walker is still holding the top spot in Iowa as of this story, so he will enter in a strong position. New Hampshire is not as strong for Walker, but he’s still sitting in the second place spot, though Donald Trump surging could rearrange the New Hampshire polls in the next couple weeks.
