I left a message for him yesterday. Talked to his staff today who assured me that my rep has not and will not vote by proxy.  His staff said that several initiatives are underway, pieces of legislation to address this proxy voting situation.  One being considered is to withhold pay of those reps who do not vote in person.  I'll try to find these bills and post separately about them. I asked my representative's staff to at least get the roll call vote documented correctly on Congress.gov so that constituents can see when their rep votes via proxy, so that voters that care can call their rep for more information why and who his proxy was.  His staff committed to bring that up to him (my rep).
