In 2012,when Wang Lijun,who is a police mayor in China fled with much information about the dictatorship of CCP to US embassy in Chengdu,the US Democrats controlled Whitehouse didn't protect him but helped communists arrest him. In Middle East,the Democrats draw army too early from Iraq,leaving too much vacuum to ISIS and other terrorists.
I think Democrats do plenty to promote liberty. If they didn't, they wouldn't be called, "Democrats."
