If your Member of Congress is on the fence about impeachment (assuming they’re a Democrat, of course, since Republicans can only vote for impeachment for Democrats per the Constitution), call or write them now. Joe Morelle, my spineless Congressman here in NY-25 (campaign motto: “Always the rearguard, never the vanguard”) finally caved a few minutes ago, according to a tweet from another constituent. I emailed his office earlier this morning.
I can think of no reasonable excuse for a safe seat Democrat not to support impeachment proceedings after the last couple of days of Ukraine revelations. Maybe some of the members in Trump districts can have a pass for now as their constituents catch up on the news, but not guys like Morelle.
