The father of ObamaCare.

(The Hill) — Democrats, not Mitt Romney, took the lead Monday in celebrating the fifth anniversary of the Massachusetts healthcare reform the former governor signed into law.

Democrats on the national and state level giddily took the opportunity to remind voters, especially conservatives, of the reforms, which they said paved the way for President Obama’s 2010 national healthcare reform law.

Brad Woodhouse, the communications director for the Democratic National Commitee (DNC), tweeted:

Thanks @mittromney, founding father of health care reform, on its 5th bday! B/c of you, nat’l health care reform is a reality! #fitn #TYMitt

Adding to the matter, the Democratic parties of Massachusetts and New Hampshire — Romney’s home state, and the first-in-the-nation primary state — will hold events to “thank” Romney for the reforms.

The Democrats are mindful of the challenges that “RomneyCare” (as critics call it) poses for the former Massachusetts governor in the Republican primary.

But Romney’s campaign-in-waiting isn’t exactly trumpeting the reforms, five years after their implementation. A spokeswoman for Romney didn’t immediately respond to an email asking whether his political operation would be doing anything to mark the occasion.
