Ann Coulter has taken my 19th Amendment thought experiment from 2003 to the next level and actually suggests that we'd all be better off it women couldn't vote.
If we took away women's right to vote, we'd never have to worry about another Democrat president. It's kind of a pipe dream, it's a personal fantasy of mine, but I don't think it's going to happen. And it is a good way of making the point that women are voting so stupidly, at least single women.It also makes the point, it is kind of embarrassing, the Democratic Party ought to be hanging its head in shame, that it has so much difficulty getting men to vote for it. I mean, you do see it’s the party of women and 'We’ll pay for health care and tuition and day care -- and here, what else can we give you, soccer moms?'
As I wrote long ago, it's an interesting thought experiment (and many women were against womens' suffrage at the time) but I'm not sure we can really use such a broad counterfactual to draw credible conclusions. After all, Communism and Fascism came from men, as do tyrannies of all sorts. Perhaps denying suffrage to women would have led to a more libertarian government but also undermined our foundation of democracy and thereby led to less stability and eventual tyranny? Who can say.
