New Virginia Senate District, Unconstitutional?

There is some chance that the new Virginia Senate district created by Senate Republicans on a 20-19 vote is unconstitiuonal.  First of all, the argument that the district was necessary to avoid a Section 2 lawsuit sounds questionable.  For starters, the geographic contortions of the Virginia Senate districts are rather obvious. Secondly, and more importantly, there are numerous proponents of the new district speaking in terms of a racial purpose in creating the district beyond purported Section 2 compliance.  Expect a lawsuit if the districts become effective.
