Sen. Ben CardinBenjamin (Ben) Louis CardinCongress passes bill to begin scenic byways renaissance GOP lawmaker: 'Dangerous' abuse of Interpol by Russia, China, Venezuela Senators pressure Trump to help end humanitarian crisis in Kashmir MORE (D-Md.) promised right out loud yesterday at a town hall meeting in Hagerstown that he will NOT vote for a healthcare bill that increases the deficit. Pretty amazing.

The Congressional Budget Office (CBO) says that ObamaCare will increase the deficit by no less than $239 billion.

Did Cardin just gift himself a get-out-of-jail-free card? After all, President Barack ObamaBarack Hussein ObamaLet's not play Charlie Brown to Iran's Lucy Mattis dodges toughest question At debate, Warren and Buttigieg tap idealism of Obama, FDR MORE claims his plan will NOT increase the deficit. CBO says it will, and they're not the only ones. When the proverbial rubber hits the road in the fall and there are votes in Congress, this may be the biggest point of contention.

Watch for Democrat after Democrat to start inching forward to grab up their get-out-of-jail-free card so they do not have to fall on their swords and vote with Obama. It'll come down to an argument over whether or not it adds to the deficit, and will be a showdown between the president and the CBO, with Democrats putting their finger in the air to see which way the wind will blow, hoping desperately the CBO prevails so that they are off the hook with their constituents.

In the end, the Democrats in Congress should remember they work for their constituents — not the president.
