Some of my views on President Obama's appointment of D.C. Circuit Court judge Merrick Garland to the Supreme Court are similar to those posted by Emily and Frank, but I would add some thoughts of my own.
Senate Republicans are certainly under no obligation to confirm Garland much less have a vote. After all, when Obama and Joe Biden were in the Senate (and for that matter Chuck Schumer) they made no bones about not confirming President Bush's judicial appointees (much less have hearings for them). What's good for the goose is good for the gander.
Yet I think such a strategy is practical if there's a good chance if Ted Cruz is elected President. Frankly, the chances of Cruz being elected President much less getting the GOP nomination are slim and none.
