I could go on and on.....
I suppose TR had little political experience other than NY gov for two years and VP for a year, but he held all kind of exeuctive titles, such as asst secretary of the Navy, President of the NYC Board of Police, US Civil Service Commission (OPM), and was a war hero to boot. Sorry Barack, you are no TR.
In fact the last person of such inexperience to hold the office was Abe Lincoln. The problem with that comparison is that Abe Lincoln is Abe Lincoln. No sane person would attempt to compare themselves to Abe Lincoln - a self educated man who worked his way up in life through strenuous manual labor. Sorry Barack, you are no Abe Lincoln either.
Does it matter.....
