I wondered that myself.
The website in her statement, sarahforalaska.com redirects to some hokey-looking fundraising website that claims to have no affiliation with any candidate.
winred.com is the fundraising base for the Republican party. but it allows the donor to target the candidates they want to support.
so while “legally” it is separate, I guess, your donations via winred are sent directly to the candidate’s campaign.
saves the candidate the trouble of having to build an internet infrastructure and fundraising arm.
All of my Trump donations were done the same way. it is legit.
The website is fine for the day of her announcement. WinRed is a standard fundraising platform for the GOP.
