Sadly it's not, he has every right to do it, and if the roles were reversed, I would expect Democrat's to do the same. So, I'm not mad at him, I'm just surprised he decided to do it this early into the term.
In 2007 and 2008 the Democratic-controlled Senate confirmed 10 GWBush´s nominees for the Courts of Appeal. This was not viewed as anything unusual. Democrats were routinely confirming GWBush nominees in 2001-2, before that Republicans were approving Bill Clinton´s nominees after 1994, Dems were in majority in the Senate during the entire GHWBush presidency and during the last two years of Reagan presidency (during which time 17 CoA and one SCOTUS nominees got confirmed).
