Every Senator takes an oath of office every year they return to the Senate, which says in part:
"without any mental reservation or purpose of evasion; and that I
will well and faithfully discharge the duties of the office"
Now that President Obama has done his job, and has nominated Merrick Garland, (currently the Chief Justice of the U.S. Court of Appeals for the District of Columbia Circuit), it's time for the Senate to just do their job, which is to advise and consent.
The following Republican Senators praised and voted to confirm Merrick Garland for the DC Circuit Court, considered the second most important court in the land: "Hatch, along with current Senators Thad Cochran (R-MS), Dan Coats (R-IN), Susan Collins (R-ME), Jim Inhofe (R-OK), John McCain (R-AZ), and Pat Roberts (R-KS)".
Judge Garland has served with such distinction that (conservative and Bush nominee) Supreme Court Chief Justice John Roberts "praised Garland’s “reasonableness”, memorably stating: “Any time Judge Garland disagrees, you know you’re in a difficult area.”
One wonders how the Republican Senators are going to get out of the corner that Senate Majority Leader Mitch McConnell (R-KY) painted them all into, right after the death of Justice Scalia. In hindsight, vowing to obstruct any attempt by President Obama to fill the Supreme Court vacancy may have been premature, not to say downright rash.
Newspaper editorial boards around the nation demand action from the Senate, while Senator McConnell ignores the cries of the nation for him to just do his job.
