Identity of the designer 

The paragraph just above the heading "Origins of the term" states:

"Intelligent design deliberately does not try to identify or name the specific agent of creation — it merely states that one (or more) must exist. Although intelligent design itself does not name the designer, the personal view of many proponents is that the designer is the Christian god.[34][22][35] Whether this was a genuine feature of the concept or just a posture taken to avoid alienating those who would separate religion from the teaching of science has been a matter of great debate between supporters and critics of intelligent design. The Kitzmiller v. Dover Area School District court ruling held the latter to be the case."

The above statement contains a popular misconception about the identity of the designer. ID leaders have indeed named the designer. 

The article's reference #34 above is to Dembski's 1999 Touchstone article in which he says that "intelligent design is just the Logos theology of John's Gospel restated in the idiom of information theory." When Dembski said that, he was identifying, indeed defining, the designer as not only God but Jesus Christ, to which "Logos" refers in the Gospel of John, as Barbara Forrest points out on pp. 3-4 of her paper http://www.centerforinquiry.net/uploads/attachments/intelligent-design.pdf.

See also the article's reference #142 at pp. 39-40 of "Is It Science Yet? Intelligent Design Creationism and the Constitution," at  http://law.wustl.edu/WULQ/83-1/p%201%20Brauer%20Forrest%20Gey%20book%20pages.pdf.  Note here also that Phillip Johnson also defines ID as requiring God when he defines it as "theistic realism."

So it is clear that it is more than "a personal view of many proponents" that the designer is the Christian God.
