They are all liars, Obama is just exceptionally well at it.
He applied for the job as the peace candidate, the marijuana candidate, the constitutional lawyer, and Mr. Transparency.
He increased the war in Afghanistan, created a death panel to determine who should be assassinated with drones, increased spending on the drug war, signed the patriot act extension, signed NDAA into law, and Mr. Transparency used Executive privilege to cover up a drug scandal through the DEA.
That's like applying for a job at the DEA and then once you get it you start selling crack.
He was elected under false pretenses and many many lies...
