I am no bleeding heat liberal but to hear Tim Oren describe himself as a centrist and have Fred endorse that view suggests to me that gravity moves in mysterious horizontal ways.
Re-classified in to UK terminology:
Fred would be an old-fashioned one-nation Conservative with slightly dodgy liberal theories or a champagne liberal - depends on your starting point.
Tim would also fit neatly in to the Consevative party grouping; that part which sits so far to the right of the one-nationers that they pass them having gone full-circle. This grouping would also hold that Gengis Khan was a little overly liberal.
None of which matters much (and its not intended as a criticism.) The point was more to demonstrate that the UK and the US have been separated by more than a similar language.
Notwithstanding, the supposedly left-wing Labour Party have sided with the Republicans (or Tony has sided with George W anyway) and the Conservative Party are trying to help Kerry (however given their (Conservative party) success recently I would personally leave them in the UK.)
