Ivanka Trump made it known this week that she had changed her voter registration from Democrat to Republican on October 22, 2018. She had missed the deadline for switching her registration in time to vote for her father in 2016. Trump was a registered Democrat until her father started pursuing the presidency. She said in April 2016 she was an Independent.
So this is an interesting timeline. Ivanka was a registered Democrat. When her father started pursuing the presidency, she did not register as a Republican – she registered as an Independent. .
