President Obama vowing that Syria would “cross a red line” by using chemical weapons is far from the only marker he’s laid down or promise he’s tried to keep since running for president in 2008.

The president has made more than 500 related-campaign promises alone. And just last week he re-drew a line in the sand for congressional Republicans trying to shutdown the government over his Affordable Care Act and looking for spending cuts as part of a separate deal to increase the federal debt limit.

“That’s not happening,” Obama said. “I will not negotiate over the full faith and credit of the United States.”

The president has had mix success in keeping that vow over the past few years.

He managed in January to get the debt ceiling raised without yielding to Republicans’ demand for accompanying spending cuts.
