Carter said that the liberal wing of the Democratic Party did not support his policies the most. He said they were caused by Ted Kennedy's plan to replace him as president. Kennedy announced his candidacy in November 1979. Kennedy surprised his supporters by running a weak campaign, and Carter won most of the primaries and won renomination. However, Kennedy gave Carter weak support from the Liberal Democrats in the fall election. Carter and Vice President Walter Mondale were formally nominated at the Democratic National Convention in New York City.
