Even though the Republican National Committee mailed Pennsylvania voters encouraging mail-in voting, describing it as a "convenient and secure” option, most Republicans expressed opposition to the prospect. Earlier, the Republican-controlled House blocked a proposal to mail every Pennsylvanian a mail-in ballot application. This was in response to President Trump's skepticism of the practice, expressing concern mail-in voting may result in voter fraud that would potentially benefit the Democratic Party.[2]
Trump was declared the winner in the Republican primary, and received all of the state's 34 pledged delegates to the 2020 Republican National Convention (the state also has 54 unpledged delegates).[4]
