Why are voters in Huntsville hosting a fundraising reception honoring Terri Sewell?

Honoring her for what?  Representing Alabama's 7th district?  What about the 5th district?  A district currently misrepresented by Mo "I'll do anything short of shooting them" Brooks (r).

The Huntsville event isn't listed on Sewell's website, but a similar fundraiser is being held in Birmingham.

I can understand the Birmingham fundraiser because it's a part of the 7th district, but why are Huntsville/Madison County democrats investing in who represents the 7th district,  and not the announced democratic candidate from the 5th district,  C.L. Holley?

How many members of Congress does the 5th district need?

What about the voters in the 7th district?  What has Sewell done for them lately? Are her constituents hosting fundraising receptions honoring Sewell?    Do they want her to continue to represent them in Congress?  Or, is this another case of the voters who don't live in the 7th district, deciding who should represent the voters who do live in the 7th district?

Psst, Huntsville Host Committee!  Help the 5th District first.  It's time for Mo to go.
