Turns out that Marco Rubio likes controversial issues. Fresh of off pissing of the majority of the conservative grassroots with his support for immigration reform, now he wants to take on abortion (who can be upset with that).
He is going to sponsor legislation that outlaws abortion after an unborn child is 20 weeks old. This measure is going nowhere in the Senate but it is a chance for Rubio to try and get back in the good graces of the conservatives he has been ticking off with his work on immigration.
Of course how it plays with swing voters in Northern Virginia or the suburbs of Columbus, Ohio, is another question.
