Not sure if you noticed but they're mostly old. They are more or less from the William F. Buckley succeeding Generation when Harvard wasn't quite so douchey.
I suppose there might be some actual conservatives that went to Harvard in Obama's day, but I would expect them to be greatly outnumbered by the Liberals.
There are fresh young conservative faces out of Harvard Law clerking for conservative U.S. Court of Appeals and Supreme Court Justices every year.
For example, being the editor-in-chief of a top law review will take you far. Rachel Miller-Ziegler, who will be clerking for Chief Justice Roberts in October Term 2016, currently is President of Volume of the Harvard Law Review. Her career in the law is set with those credentials.
Justice Scalia has hired Harvard Law Grads Michael Kenneally and Sean Mirski; Justice Thomas has Sarah Harris; Justice Alito has Clarence Walker; Justice Kennedy has Alex Harris; and Justice Roberts has Katherine Booth Wellington and the aforementioned Rachel Miller-Ziegler.
These are all names to watch for the future.
