With Obama's re-election, several states legalizing the freedom to marry by popular vote, and public opinion, Justice Kennedy's favorable LGBT leanings will definitely be pushed for a big leap towards sanity.
All the lower court opinions have been striking down DOMA. Justice Kennedy sided with liberals on most LGBT issues. He has the slightest bit of sanity on social issues at least. That is why conservatives do not trust him. That is also why conservatives have not yet tried to overturn Roe vs Wade in the courts. They do NOT trust Kennedy, who has always maintained the slightest upholding of Roe even while chipping at its sides.
America dodged a HUGE bullet on election day. The Supreme Court's rightward drift has hit a huge thud. President Obama's re-election, his filling of the remaining vacancies with sane judges in the new senate, and grassroots organizing of leftward pressure for public opinion, and progressive government building from the bottom up (local governments/councils and state governments/legislatures) should eventually pave the way for a liberal supreme court aided by another two-term Democratic President after Obama.
The conservative supreme court justices will not retire under Obama. They will not give in right way. However, the ground has shifted such that the court will flip in the long-term, provided that the left is vigilant, aggressive, and persistant. That is how the right got so powerful.
