Scott's Poll-Crunch has a new number.
The Mandate Number. This number is based on Presidential poll numbers from Presidents that did infact have demonstratable mandates to do stuff. Like Frank Roosevelt.
The Mandate Bar is set at 70% approval
If a President wants to go on TV and tout a mandate from the American electorate he better have poll numbers like this. If not then all that talk is hot air only.
Using this number Bush had a mandate from Sept. 11th 2001 until about Christmas time of that year. After that his numbers plummeted to 43% in 2003 and have not really recovered. Clinton's outgoing poll numbers had Clinton at 65% approval after impeachment.
