With President Obama's nomination of Merrick Garland as the new Supreme Court Justice, the evenly split court threatens to tilt left for the first time in decades.
To further complicate matters, Senate Majority Leader Mitch McConnell refused to consider Garland's nomination in hopes a Republican candidate becomes president and makes the selection instead.
Glenn considered Republican Party's move unwise to say the least.
"You don't play it that way," he said on his radio program Wednesday.
"It's stupid," co-host Pat Gray added.
Putting his political buff hat on, Glenn reminded the Senate their job is to "advise and consent" while the president's job is to nominate.
"Here's how you play it," Glenn said. "He's going to nominate and we'll look at every person --- we'll look at them seriously. Then when they come up, you've done your part and say, 'no, he's not the right guy.'"
How hard would that be? Too hard, apparently. The leaders of the GOP have made their choice.
"The good news is, last night was the final nail in the coffin of the GOP," Glenn said. "You voted them out last night."
