Jon Lieber, who leads Eurasia Group's coverage of political and policy developments in Washington, offers insights on the Supreme Court vacancy:

Will Senate Republicans, who stopped a Supreme Court nomination in 2016, because it was too close to an election, pay a political price for the change in tactics this time around?

Not only do I think they won't pay a political price, I think in many cases, they're going to benefit. Changing the balance of power on the Supreme Court has been a career-long quest for many conservatives and many Republicans. And that's why you've seen so many of them fall in line behind the President's nomination before we even know who it is.

At this point, do Senate Democrats have any hope of stopping President Trump from filling the ninth seat on the Supreme Court?
