I would LOVE to see a list of how those who have to face the voters in barely a month as opposed to those who are still a couple years away from an election. My senses tell me those who are up to bat Nov. 4th had a remarkably different to this problem from those who are safe for now. If that’s the case then it just shows once again how effective term limits would be if applied by the voters much more frequently!
Congressmen face voters every two years & this is the year, so the answer to your question is 100%. A better question to ask would be how many in “unsafe” districts voted for it.
