I'm going to be repeating this whenever this ad blitz is mentioned because it is MUCH WORSE than you think. America PAC is partially funded by Musk and his old pals at Palantir. They sell data and analyses of it. You might get registered to vote if your state is a solid red or blue, but CNBC reports (archive):
[...] users who enter a ZIP code that indicates they live in a battleground state, like Pennsylvania or Georgia, the process is very different.
Rather than be directed to their state’s voter registration page, they instead are directed to a highly detailed personal information form, prompted to enter their address, cellphone number and age.
So that person who wanted help registering to vote? In the end, they got no help at all registering. But they did hand over priceless personal data to a political operation.
“What makes America PAC more unique: it is a billionaire-backed super PAC focused on door-to-door canvassing, which it can conduct in coordination with a presidential campaign,” Fischer said. “Thanks to a recent FEC advisory opinion, America PAC may legally coordinate its canvassing activities with the Trump campaign — meaning, among other things, that the Trump campaign may provide America PAC with the literature and scripts to make sure their efforts are consistent.”
The America PAC raised more than $8 million between April 1 and June 30, according to FEC records. It has received donations from veteran investor Doug Leone, cryptocurrency investors Cameron and Tyler Winklevoss, and a company run by longtime venture capitalist Joe Lonsdale, according to FEC records.
They also quote the NYT in saying Lonsdale is one of Musk's political confidants -- which is interesting because he's at Palantir which was you'd think of as his buddy Peter Theil's gig. Again, Palantir sells information, so in all likelihood they are going to take that input to figure out exactly how to target people to 'vote Trump' using the very information the public gave them for free!
It's because of the electoral college. Most states give all their electoral college votes to whomever wins the state rather than dividing the votes equitably. This means Pennsylvania -- a swing state -- will go either all-red or all-blue. The state has a lot of fracking, and a lot of people making money off it, so Democrats are trying to appease pro-fracking to get votes.
The people getting harmed by fracking are stuck without anyone on their 'side', but will presumably be more likely to vote blue because that side favors more regulation and pro-environment stuff. Note that all Harris said was she wouldn't ban fracking. She didn't say she wouldn't make it difficult to do. My guess is any attempts to make it cleaner will get crushed by Congress and the Corrupted Supreme Court that has sided against Unions, workers, citizens, and the planet -- all to favor of their sugar daddies. So even if the next President wants to do something about fracking, it would be a hard to actually do anything.
