Yep, the last campaign was about Elizabeth Warren’s belief (probably accurate) that she had some American Indian ancestry, and this time, he’s running again, and he’s leading with an attack on Ed Markey’s Massachusetts residency:

Senator Scott Brown today took on a possible opponent in a special election to succeed his colleague John F. Kerry, questioning whether US Representative Edward J. Markey is actually a resident of Massachusetts.

Markey later hit back, hinting at a reprise of the political nastiness that permeated Brown’s recent election battle against Democrat Elizabeth Warren.

Brown has suggested he would compete in the special election that will be triggered if Kerry is confirmed as President Obama’s second-term secretary of state, but he has not made a formal commitment to a race. Markey has already said he will run.

“I’ll tell you what; They’re making it awfully tempting. You got Ed Markey: Does he even live here any more?” Brown said with a laugh as he called into the “Jim & Margery Show” on WTKK-FM.

“You’ve got to check the travel records. I’ve come back and forth (from Washington to Boston) every weekend, almost, for three years, and I see, you know, most of the delegation, and I have never seen Ed on the airplane – ever,” Brown added.

Markey, a Democrat born and raised in Malden, long called his childhood bedroom in his parents’ house as his Massachusetts residence, even though his wife, Susan Blumenthal, was a doctor at the National Institutes of Health in suburban Washington and the couple owns a home in Chevy Chase, Md. Blumenthal is now a health care consultant.

Seriously, another episode of, “Of course she’s not Indian, look at her?”

I Really do not get this. His primary asset is his appearance of likability, and he’s coming across like an entitled frat boy from the movie Animal House.

This is not just nasty, it’s stupid nasty. I do not get it.

H/t TPM.
