Not long ago The Washington Post was digging up rocks from 30 years ago to find dirt about Rick Perry.

Now WaPo is digging up immigration papers from 50 years ago about Marco Rubio’s parents, Marco Rubio’s compelling family story embellishes facts, documents show.  The gist of WaPo’s dramatic claim is that Rubio’s family did not leave Cuba after Castro took power, but two years before Casto took power.  Thus, according to WaPo, Rubio’s family narrative of being Cuban exiles is embellished if not false.  WaPo does quote Rubio as saying that his family attempted to return to Cuba after Castro took power but that they left because they didn’t want to live under Communist rule.

The Miami Herald, however, points out that it is WaPo which is embellishing, not Rubio, Did the Washington Post embellish Marco Rubio’s ’embellishments’? The Herald points out that the one speech which WaPo cites as to Rubio telling the story of his family fleeing Cuba after Castro does not actually say what WaPo says it said.  The Herald also makes the completely accurate point that even Cubans who left just prior to Castro could not return unless they wanted to live under Communism, and that it it proper to refer to them as exiles.

But there is a bigger point here.  Look how carefully WaPo is scrutinizing not just actual Republican candidates like Perry, but potential candidates in some future election cycle like Rubio.

WaPo can turn over rocks on Perry, and dig deep into half-century old immigration files as to Rubio, but WaPo was dragged kicking and screaming into even touching Barack Obama’s 20-year association with Jeremiah Wright, as Jim Geraghty of NRO tweets:

The article linked in Geraghty’s tweet is a mea culpa from WaPo’s ombudsman about WaPo’s delay on the Reverend Wright story, When The Post Was Late to Church:

The Post — and some others in the news media — came late to reporting on the controversy surrounding the Rev. Jeremiah A. Wright Jr., Barack Obama’s former Chicago pastor. The story, long there for the picking, touched raw nerves — racial, political and religious — among readers.

WaPo should be digging as to actual and potential presidential candidates.  The issue is not where WaPo has been digging, but where it has not been digging.

Put it all back on the table, starting Obama’s Jeremiah Wright years and Obama’s claims that he never heard any of Wright’s inflammatory speeches.  Interview parishioners, obtain audio and video records, dig anywhere and everywhere regarding Obama’s completely implausible claim that he didn’t know his spiritual mentor was a race-baiting flame-throwing agitator.  And while WaPo’s at it, dig into Obama’s relationship with Bill Ayers and Bernadette Dorn; Obama’s early campaigns; the land deal with Tony Reszko through which Obama bought his house on the cheap; and Obama’s mystery college years.

It’s all there for WaPo’s investigative journalists and page one headline writers.  And it’s all back on the table.
