In the 2010s, following the revelations by Edward Snowden about NSA surveillance in 2013, the increasing advent of online decentralization and cryptocurrencies like Bitcoin, the perceived failure of the war on drugs and the police violence in places like Ferguson, Democratic lawmakers such as Senators Ron Wyden, Kirsten Gilibrand and Cory Booker and Representative Jared Polis have worked alongside libertarian Republicans like Senator Rand Paul and Representative Justin Amash to curb what is seen as government overreach in each of these areas, earning plaudits from such traditional libertarian sources as "Reason" magazine. The growing political power of Silicon Valley, a longtime Democratic stronghold that is friendly to economic deregulation and strong civil liberties protections while maintaining traditionally liberal views on social issues, has also seriously affected the increasingly libertarian leanings of young Democrats.
