“Sen. Mike Mansfield, (D-Mont.), the majority leader, was quoted yesterday as insisting he was going to keep the Senate working 12 hours a day and more — even if it meant missing the opening baseball game,” The Post’s Bob Addie wrote in early April 1964, 50 years ago this spring. The columnist went on:

Sen. Mansfield was in the Presidential party along with another keep-your-nose-to-the-grindstone man, Sen. Hubert Humphrey (D-Minn.), Sen. Everett Dirksen and Sen. George Smathers (D-Fla.).

Along about the fourth inning, public address man Charlie Brotman announced that there was a quorum call on the civil rights bill in the Senate. Senators Mansfield, Humphrey, Dirksen and Smathers sheepishly left the stadium like little boys caught playing hookey. Now, aren’t you glad you’re just nobody and got to see the whole game?

Out-of-town visitors, and there were many, always are awed by the brass at one of these Washington openers. Just think — this all happens even when the Senators finish last. If they should ever win the pennant, the World Series here probably would have mostly kings and queens and be by invitation only.

The point being, members of Congress have had a hankering for baseball for decades upon decades. And with another opening day approaching, the fine folks at C-SPAN went through their video library to cull dozens of examples of Senators and Representatives talking ball on the Hill.
