He once declared that Taylor Swift was "terrific". But in a childish jape that only makes him look even more pathetic, US President Donald Trump has bizarrely stated that he now likes her music "25 percent less" because she publicly backed two Democrat candidates!

"Marsha Blackburn (the Republican Senator) is doing a very good job in Tennessee. She's leading now, substantially, as she should. She's a tremendous woman. I am sure Taylor Swift does not know anything about her and let's say that I like Taylor's music 25% less now," stated Trump, who declared back in 2012 that Taylor Swift is "terrific".

Taylor Swift, usually known for maintaining an apolitical stance in public, decided last Sunday night to use her Instagram account to threw her support behind Democrat candidates Phil Bredesen for Senate and Jim Cooper for the US House.

During the 2016 election, Taylor Swift urged fans to vote, but wouldn't reveal how she would cast her own ballot, which, at the time, resulted in one of the top Google searches being “Who is Taylor Swift voting for?”

“In the past I’ve been reluctant to publicly voice my political opinions. I feel very differently about that now," Taylor stated on Sunday.

"I always have and always will cast my vote based on which candidate will protect and fight for the human rights I believe we all deserve in this country. I believe in the fight for LGBTQ rights, and that any form of discrimination based on sexual orientation or gender is WRONG.

“I believe that the systemic racism we still see in this country towards people of color is terrifying, sickening and prevalent.”

Whatever about free speech, other prominent Republic Party members are now vocally criticising Taylor for endorsing the two Democrats. The National Republican Senatorial Committee commented, “If you haven’t heard, multimillionaire pop star Taylor Swift came down from her ivory tower to tell hardworking Tennesseans to vote for Phil Bredesen."

While the president of conservative group Turning Point USA, Charlie Kirk tweeted: “You just endorsed a Democrat in the Tennessee Senate race with a ridiculous statement saying Marsha Blackburn, a woman, is against women. You have absolutely no idea what you are talking about.”

But others have been quick to jump to Taylor's defence. Spinal Tap director Rob Reiner tweeted: “A big shout out to Taylor Swift for speaking out. You can single handedly change this country. Impress on your fans how critical and powerful their voices are. If you get them to the polls on Nov 6, everything you care about will be protected.”

Phil Bredesen thanked the pop star, tweeting: “I’m honored to have your support and that of so many Tennesseans who are ready to put aside the partisan shouting and get things done. We’re ready for it.”

However, such celebrity endorsements don't always work in a candidate's favour. In the 2016 Presidential election, Hillary Clinton was publicly endorsed by Bruce Springsteen in Pennsylvania, Jennifer Lopez in Florida, and Jay-Z and Beyoncé in Ohio... yet all three states went to Trump.

I’m writing this post about the upcoming midterm elections on November 6th, in which I’ll be voting in the state of Tennessee. In the past I’ve been reluctant to publicly voice my political opinions, but due to several events in my life and in the world in the past two years, I feel very differently about that now. I always have and always will cast my vote based on which candidate will protect and fight for the human rights I believe we all deserve in this country. I believe in the fight for LGBTQ rights, and that any form of discrimination based on sexual orientation or gender is WRONG. I believe that the systemic racism we still see in this country towards people of color is terrifying, sickening and prevalent. I cannot vote for someone who will not be willing to fight for dignity for ALL Americans, no matter their skin color, gender or who they love. Running for Senate in the state of Tennessee is a woman named Marsha Blackburn. As much as I have in the past and would like to continue voting for women in office, I cannot support Marsha Blackburn. Her voting record in Congress appalls and terrifies me. She voted against equal pay for women. She voted against the Reauthorization of the Violence Against Women Act, which attempts to protect women from domestic violence, stalking, and date rape. She believes businesses have a right to refuse service to gay couples. She also believes they should not have the right to marry. These are not MY Tennessee values. I will be voting for Phil Bredesen for Senate and Jim Cooper for House of Representatives. Please, please educate yourself on the candidates running in your state and vote based on who most closely represents your values. For a lot of us, we may never find a candidate or party with whom we agree 100% on every issue, but we have to vote anyway. So many intelligent, thoughtful, self-possessed people have turned 18 in the past two years and now have the right and privilege to make their vote count. But first you need to register, which is quick and easy to do. October 9th is the LAST DAY to register to vote in the state of TN. Go to vote.org and you can find all the info. Happy Voting! 🗳😃🌈
