Supposedly, he's being reluctant to make another run which has the GOP in a bit of a panic since without him their chance of taking the seat is approximately nil.
He's in an awkward position for some inside baseball state political stuff. The Democratic Primary is a bit of a squeeze play this time. If Brown doesn't run, Ed Markey likes wins, who would be a weakish candidate against Brown. He's a machine guy, the prototype emasculate liberal elite. John Kerry without the charisma. Really. If Brown does decide to run, Stevie Lynch probably wins the primary and Brown loses 90% of the white Catholic vote and the election by 20. He could probably beat Markey, but it's not like he can wait until after the primary to decide to run or not.
To make a long story short, I don't take any responsibility for anything I post here. It's not news, it's not truth, it's not serious. It's parody. It's satire. It's bitter. It's angsty. Your mother's a whore. You like to jack off dogs. That's right, you heard me. You like to grab that dog by the bone and rub it like a ski pole. Your dad? Gay. Your priest? Straight. @#%^ off and let me post. It's not true, it's all in good fun. Now go away.
