If so he might well have been disappointed
Well possible, though ... could have anyone known or even guessed it 1914/1915 ?
Opinion polling was barely starting then, but such research as was done suggested that most of the newly enfranchised women were voting Conservative. This, of course, was why a Tory government would give them the right to vote at the same age as men in 1928.
Is it possible that women voted Conservative - and not Liberal - as the Liberals had self-destructed by that point?
That women got the vote when voters had a choice between Tory or Labour ...
Do you have a source for that ?
If I compare the electorial behavior in Germany, when women had the full right to vote in 1919 (National aka Constitutional Assembly) as well as 1920 (1st Reichstag) it seems they voted at their frist opportunity rather for the party "giving" them the right to vote (SPD and Liberal Democrats), while at the second opportunity they seems to have "shifted" from Liberal more to the conservatives (the "Left" (combined SPD, USPD and in 1920 also KPD) were more or less the "same" 187 seats in 1919 and 190 seats in 1920).
Compared to british 'circumstances' you would have the party "giving" the women the vote (Liberals) instead the party more thoroughly denying them partition in the political life (Tory).
Also, you have lesser possible (female) voters for lLabour, as they would more likely NOT come from a "working class"/"low(er) wages" background (... as many women did in Germany in 1919 and 1920).
Also in 1918, when women (though still only if "qualifying" by age, property, 'income' measured in ability to pay rent) in Britain could vote the first time, the 'Liberals' and what they stood for were split up into 'Coalition Liberals', 'Liberals', Coalition National Democrats, Independants Liberal' and 'National Democrats'.
There simply was no other choice that Tory and/or Labour.
And given, that the Torys 'raised' their popular vote even well below doubling it (as the electorate as a whole was raised in 1918 somewhat shortly above dubling) and Labour increased its share almost 7-fold - all compared to the last pre-war election - I would wonder, if this female electorate actually voted "more conservative".
