The Dems are better. They are better than republicans on this, but they certainly aren't good enough. That is the unfortunate part. But if you definitely want a better chance for civil liberties, voting for R's will hurt you worse than if you vote for D's, significantly so.

I suppose that depends which civil liberties are more important to you. You'll find that Democrats are pretty awful if you value your right to self-defense, or if you don't think the government should be able to use eminent domain to take your property and give it to a wealthy supporter.

Some of the details may be different, but they're both different sides of the same coin. I don't see that one side is significantly better than the other overall.
