I signed.
On the previous 3 attacks in the last month, I contacted my senators each time. Sen Blunt (R) made statements in favor of bike/ped. Sen McCaskill (D) never said a thing. (In the past she's been against bike/ped). However, on the last bill that actually came to a vote, they voted along party lines. She voted against the bill (and for bike/ped), Blunt voted for it. Fortunately it was defeated. But I was very disappointed in him after he'd made all these statements-- including one right before the vote in an email to me (and other constituents who contacted him)-- in favor of bike/ped.
This year has just been one long struggle to keep our ground in the face of the attacks. That's frustrating after we'd been making progress in the past few years.
