I just stole the paragraph below from Josh Marshall's website because I thought it was worth quoting in full…
You'll hear a lot today about how since 1322 or whenever it is, only three men have lost the New Hampshire primary and gone on to be president. But definitely pay attention to who the three are: Clinton, Bush and Obama. In other words, the last three presidents, going back 24 years. So yeah, the New Hampshire primary ain't what it used to be.
And keep in mind that no matter who the nominees are, there's going to be some precedent-breaking. If the Democratic nominee is Hillary Clinton, you'll hear, "This country has never elected a woman president" If it's Bernie Sanders, you'll hear, "This country has never elected an admitted Democratic Socialist."
If the Republican nominee is Donald Trump, you'll hear, "This country has never elected a man with no experience in government or the military." If it's Ted Cruz or Marco Rubio, you'll hear, "This country has never elected a person of Hispanic ancestry."
Just like not long ago, it was "This country has never elected a black man." There's a first time for everything except President Jim Gilmore.
