Go back 2007/2008. The speeches she gave were OK...but simply not Bill Clinton or Barak Obama type speeches. The debates? She was marginally capable of arguing and depended on softball-type questions by the moderator to survive each debate. She basically allowed a no-name senator to walk all over the Iowa campaign platform and easily beat her.
For anyone who thinks she has the charm or charisma of Bill Clinton...they are woefully wrong. You can run for Senator in New York state, with marginal Republican opposition, and almost zero Democratic opposition....and her charm level will work. Taking that to the national level? No....it simply doesn’t work.
President Bill Clinton bought that election for her with money and pardons.
