JEB! has been rightly excoriated for picking on Marco Rubio’s Senate attendance record in last night’s debate and Rubio deserves credit — from a debating standpoint — for his clever rebuttal. Given that JEB!’s attack was obviously pre-planned, it seems like he was advised poorly by whomever was preparing him for the debate.
From a tactical perspective, a better approach for JEB! to win over Republican voters would be to paint Rubio 2016 as equivalent to Obama 2008. Imagine if he had said something like this:
“If we’ve learned anything during the last eight years, it’s that half a term in the Senate is not sufficient experience to be President. Marco, you may offer Obama-esque rhetoric about youthful optimism, but President of the United States is not the place for you to get on-the-job training.”
