I for one would very much like to see Drew back in Parliament. But Carmichael clearly has other worries, and he has good cause to have them.
Every constituency in a Remain area, but for which the MP voted for Second Reading last night, is now a Liberal Democrat target seat.
Overwhelmingly, those MPs are Conservatives in the South of England.
Using the NHS excuse to abstain, at least, at Third Reading might very well be their last hope of remaining in Parliament after 2020.
It might also be enough to kill this Bill.
Thereby requiring the Government to produce one that did indeed honour the result of the referendum: withdrawal from the EU, leading to an extra £350 million per week for the NHS.
Or face defeat at the polls overall by the party that would do precisely that.
