Because Wikipedia tends to err on the side of respecting the wishes of the subject. For a less political example, CPG Grey's page doesn't have his legal name or photo despite them being pretty easy to find.
Unless that subject is right wing.
Wolf Blitzer:
>Wolf Isaac Blitzer (born March 22, 1948) is an American journalist, television news anchor, and author who has been a CNN reporter since 1990, and who currently serves as one of the principal anchors at the network.[1] He is the host of The Situation Room with Wolf Blitzer and until 2021, served as the network's lead political anchor.
Seems fine, right?
Tucker Carlson:
>Tucker Swanson McNear Carlson[5] (born May 16, 1969) is an American television host, conservative political commentator and author who has hosted the nightly political talk show Tucker Carlson Tonight on Fox News since 2016.
But Tucker is labelled conservative.

And you don't have to be right wing to see this. I'm a registered Pacific Green.
>Rachel Anne Maddow (/ˈmædoʊ/ (listen), MAD-oh; born April 1, 1973) is an American television news program host and liberal political commentator.
Maddow has used the same defense against litigation as Carlson. The 'conservative/liberal' tag is applied when a person is described as a political commentator.
I don't, and I think this myth among so many in "news" media has done more to misinform people than any of the pundits who are honest about their biases. See also, Dan Rather and Brian Williams.
In this case, both Maddow and Carlson have used the argument in court that a reasonable person would not take what they say as fact. Regardless of our personal opinions about him or his employers, Blitzer has not made that claim.
If we're trying to ascertain whether Wikipedia is biased in how it describes people on television, comparing a political commentator to a journalist is not going to be a very instructive example. Comparing to another political commentator is going to be more useful. I'm not making any assertions about how I feel regarding these people.
Having the same bias as Wikipedia isn't evidence of their impartiality.
