Why the IRS targeted the Tea Party

Perhaps this letter from eight sitting US senators had something to do with it.  Dated February of last year and signed by the likes of Charlie Schumer (D-NY) Al Franken (D-MidwestSomeplace) and our very own Jeanne Shaheen (D-NH)  and four others, it complains that organizations applying for tax exempt status under 501(c)4 are actually sinister political organizations trying to dodge taxes.  It goes on to urge an IRS crackdown on them.   Although addressed to the then IRS commissioner, Douglas Shulman, want to bet the content of the letter was shared around the IRS internal grapevine?   And a bunch of the usual leftie greenie democratic bureaucrats decided to do something about it?  I mean when you have seven US senators egging you on, it cannot be illegal can it?
  Be careful what you ask for.
  And we really need to get out republican votes against our senator Jeanne Shaheen.  Any one who would join forces with the likes of Charlie Schumer and Al Franken cannot be good for New Hampshire.  She is up for re election in 2014.
