Politico's June 15, 2023 ‘Blood on your hands’: Duckworth blasts Sinema for pilot training proposal contains the following sentence:
Sinema, who caucuses with the Democrats, did not immediately have any comment.
US Senator (Arizona) Kyrsten Sinema was a Democrat but in December 2022 became an Independent.
The phrase "Caucusing with the Democrats" has a certain poetic "ring" to it, like Van Halen's Runnin' With The Devil.
Question: But from a strictly behavioral point of view, what specific activities constitutes "caucusing with the Democrats"?
Does it involve things like meetings? Cooperation/working together? Sharing information? Sharing funds or resources? The actual side of the isle that the Senator would physically sit on in the Senate chamber?
Are there any specific activities that would preclude their behavior being called "caucusing"? Voting patterns? Rhetoric? Campaign activities or avoidance thereof?
