Have you not heard of a router? Sure i have an internet connection but i wouldnt have to. Lots of people have subnetworks that are isolated from outside network access, and my router would still be able to stream from my computer to my laptop even if my internet was down or i unplugged the modem. The last time they did scheduled maintenance on my internet thats exactly what i did, i streamed things that i had previously downloaded and saved on a different computer.
The only leverage you have as a voter is to not commit too early. Show that youre willing to support kamala no matter what, and she wont move an inch on her policies. But if polls show her starting o lag behind, regardless of how people will actually vote when push comes to shove, the maybe, just maybe, shell make some concessions, like not supporting genocide. All of these “never trump, blue no matter who, kamala girlboss power” voters are just throwing away the only chance you have to actually maybe sway things in a better direction.
