Undermines ideals of democracy.
Hmmm, lets see:
1) In 2009, Obama stood silent as Iran's government brutality put down protesters, and even applauded an 'election' won through political repression.
2) Every year Obama has actively pushed for more foreign aid for Azerbaijan, a country which routinely arrests journalists and is a dictatorship with no opposition.
3) Obama claims to believe in 'human rights' but signed the patriot act, which obviously violates them.
4) Obama funded 'rebels' in Syria to overthrow Assad, and turned a relative stable country ruled by a repressive secular dictator, into a sectarian country of which a third is ruled by ISIS.
5) Obama was silent despite ongoing political repression, and the imprisonment of thousands of journalists, intellectuals, politicians and even children in Turkey.
6) Supported the overthrow of Mubarak, and then the repressive Muslim Brotherhood's government in Egypt, which tried to set up an Islamic state. Egypt now has a military dictatorship, in all but name.
7) Obama like past presidents turns a blind eye to the status of democracy in most US allies, but condemns the allies of US rivals like Russia or China.
8) Obama supported the overthrow of Ukrainian government, which later led to civil war and a humanitarian catastrophe, where human rights are violated by both sides.
9) Attempts to interfere in the Israeli elections, by privately endorsing and supporting Netanyahu's political rivals.
So, kinda ironic for Obama to rave against Israeli elections, and claim they were undemocratic. When a lot his administration's actions have been to either ignore or endorse political repression over the years.
