@bobsal u1553115,
We don't have a presidential system, the only people who could actually vote for Blair or Thatcher were their own constituents.
I voted for Blair for party leader and initially he did a damn good job, Kosovo, Sierra Leone, Northern Ireland, introduction of tax credits and massive investment in Education and Health.
After Bush came in it went downhill, and my MP, John Denham, the guy I could vote for resigned from the cabinet because of Iraq, so I still voted for him.
The Tories would have been even more supine than Blair.
