NOTABLES:

And another group, Crossroads GPS, announced this weekend they would be unveiling specific ads targeting House and Senate candidates on the health care issue. Heres one calling on North Dakota Senate candidate Heidi Heitkamp to support repeal of the law. The ad is titled Tax, and was updated to reflects the courts ruling. WATCH: http://bit.ly/LUFyaE

THE NOTE:

Its a bird, its a plane! Its a tax, its a penalty!

Ever since last Thursdays Supreme Court decision that ruled the Obama administrations signature health care reform law constitutional, both Democrats and Republicans laced up their running shoes for a sprint to the dictionary.

The keyword: tax.

Republicans want to bake the idea that the health care law imposes a tax into the cake. While Democrats, on the other hand, are loathe to refer to it in those terms.

White House Chief of Staff Jack Lew insisted, repeatedly, in interviews this weekend that under the law refusal to buy insurance would amount to a penalty and Obama campaign aides echoed the White House line, calling it a a free loader penalty.
