Answer:
29% of registered voters between 2018 - 2019 are affiliated with the Republican Party. According to the census conducted by Pew Research Center.
Step-by-step explanation:
It is common that in years close to an election, some institutions carry out census that are able to determine what the population's preferences are in relation to voting intentions and affiliation to political parties. Between 20018 and 2019 the Pew Research Center started a survey on the possibility of the American population to register to vote and to join one of the existing political parties. This census found that 34% of US citizens registered to vote have no political party affiliation. 33% had affiliation with the Democratic Party, while 29% had affiliation with the Republican Party.
