Hey now! Didn’t you hear about the strongly worded letter?? Zzzz

Nope, you have it the wrong way around. They want to appear to be on the “right” side even when they’ve done everything they can to fight it. A clear record of how they voted (which is a good thing for plenty of other reasons) is just more incentive to vote the popular way when they can’t win.

Voting record isn’t as useful as you’d think. They tend to vote for policy they don’t like when they don’t have the numbers to stop it. Purely so they can take credit for a popular thing they fought against.
