I’m not sure how serious Coulter is about her claim, but voter demographics from the 2012 election clearly show that if only men had voted, Romney would have won.

Here’s some more demographics that show if only women had been allowed to vote, both Gore and Kerry would have won. They also show that there have been exceptions. For example, if only women had been allowed to vote in 1960, Nixon would have won, Kennedy would have lost.

Every woman I know voted for Romney and that includes a couple who finally admitted they had voted for zer0 the 1st time.
Even some men I know who are business owners and should have voted GOP hang on to their “cool” image (in their own minds)and defend their worst enemy. They are a minority, I admit. But I hear way more whining about *fairness*, especially as regards income (!) from men, than from women.
Anecdote, not data.
