Personally the census never really bothered me too much to be honest, but it does seem that the White House supervising it, strikes me a little as turing something that should be non-political into something political.
It's always been political. That's why sampling isn't used even though it's far more accurate.
In doing so, it appears to make some a little skeptical as to the real purpose of the data then. If it is to be used to determine the number of Congressmen for each state then fine, but as a means to draw the lines in one partys favor or the other, then no. That is the reason why the census need only known the number really, the other data is not really needed other than for political purposes.
Why would they need the other data for political purposes? The most politically relevant data (election results) are something they already have access to. Besides, it's the states, not the federal government, that set up the districts.
