That's a sharp rise for a single-day period compared to the number of new registrations made in the full months of September and August, which saw 190,178 and 56,669 new voters registered in total, respectively.
Taylor Swift making a rare political statement has apparently inspired a big surge in voter registrations - and luckily Vote.org was ready for it.
In Tennessee, she said 2,144 new registrations came in the last 36 hours.
Guthrie said traffic to her organization increased after Swift's post, with 155,940 unique visitors coming to Vote.org in the 24 hours following, compared to the average number of daily users of 14,078.
The Speak Now singer said she was a supporter of gay rights and women's rights, and against racism.
"She voted against the reauthorisation of the Violence Against Women Act, which attempts to protect women from domestic violence, stalking, and date rape". But they also enraged many conservatives, especially those in the country music community where Swift got her start as a teenager and went on to win 10 Grammys.
"Thank God for Taylor Swift", Guthrie said.
"These are not MY Tennessee values", the "Fearless" singer said online.
Donald Trump couldn't resist from clapping back at Taylor Swift after the popstar broke her silence on her political views for the first time to back two Democratic politicians in the upcoming mid-term elections, while criticising a Republican candidate. "Her voting record in Congress appalls and terrifies me", Swift writes. Voting is not the habit for young Americans that it is for others, so it's critical to remind them that in every congressional district and state on November 6, guns will be on the ballot - as will jobs, health care, gender equity and empowerment, education, student loans and the kind of capitalism they want to see practiced in the United States.
Swift and Bredesen have also worked together in the past: Earlier this year, Bredesen posted an old group photo featuring the two and wrote, "In honor of #NationalPoliceWeek, here's a #TBT from when [Taylor Swift] & I joined the TN Assoc. of Police to launch 'Delete Online Predators, ' an education campaign to combat Internet crimes against children". He told reporters on Monday that he likes "Taylor's music about 25 percent less now". In doing so, Kirk not only presents those issues disingenuously (Bredesen did support Kavanaugh but the sexual harassment issue was far more complicated than he presented it to be), but he's ignoring Swift's message that while you might not find your dream candidate, that doesn't negate the importance of voting.
