The Post's "In The Loop" team has a good recap of the longest filibusters in history. So where did Sen. Rand Paul's (R-Ky.) rank when all was said and done?
In short: It appears he delivered the 9th-longest filibuster in recorded history (though we can't be sure because the Senate historian says its current list may not be comprehensive).
Paul stopped speaking around 12:40 a.m., just shy of the 13-hour mark, clocking in at 12 hours and 52 minutes.
If he could have kept talking until 2:01 a.m., he would have passed Sen. Robert Byrd (D-W.Va.) for the eighth-longest filibuster ever; if he had still been speaking at 3:02 a.m., he would have eclipsed Sen. Alphonse D'Amato (R-N.Y.) for seventh-longest; and if he spoke until 3:18 a.m., he would have passed Sen. Huey Long (D-La.) for the sixth-longest.
Here are the updated standings for longest filibuster:
1. Sen. Strom Thurmond (D-S.C.) (1957): 24 hours, 18 minutes
2. D'Amato (1986): 23:30
3. Sen. Wayne Morse (I-Ore.) (1953): 22:26
4. Sen. Robert La Follette (R-Wis.) (1908): 18:23
5. Sen. William Proxmire (D-Wis.) (1981): 16:12
6. Long (1935): 15:30
7. D'Amato (1992): 15:14
8. Byrd (1964): 14:13
9. Paul (2013): 12:52
