Who is Watch Black Water: Abyss Onlineafraid of little old Taylor Swift? After Tuesday night, Republicans should be.

After the presidential debate between Vice President Kamala Harris and former President Donald Trump on Sept. 10, Swift took to Instagram to publicly endorse Harris. But she didn't stop there. The popstar also added a custom voter registration link to her Instagram story. As of 2 p.m. ET Wednesday, 337,826 people visited that link, the General Services Administration told NBC News.

The URL takes people to vote.gov, a website with information on how to register to vote and update voter registration. It also details voting rights and answers frequently asked questions.

In her endorsement post Swift wrote, "I will be casting my vote for Kamala Harris and Tim Walz in the 2024 Presidential Election. I’m voting for @kamalaharris because she fights for the rights and causes I believe need a warrior to champion them." Then she encouraged her 284 million followers to do their own research and vote for whoever they'd like to. "Remember that in order to vote, you have to be registered! I also find it’s much easier to vote early. I’ll link where to register and find early voting dates and info in my story," concluded her post which now has over 10 million likes.
