Does someone have a white horse he can ride in on? The late West Virginia Sen. Robert Byrd’s successor, Carte Goodwin, arrives in Washington Tuesday and will give Democrats the votes they need to extend unemployment benefits. He comes just one day after President Obama took Republicans to task for filibustering the measure. At least two Republicans, Maine Senators Susan Collins and Olympia Snowe, are expected to join Democrats in voting to break the GOP filibuster. If the measure passes as expected, 2.5 million jobless Americans will receive benefits retroactively.
