Trump, who is running almost unopposed, gained 94.3 percent of the vote and 122 delegates in Florida, according to CNN Tuesday. NBC News projects him to also win in Illinois with 94.9 percent of the vote and 66 delegates.
Both wins give him 188 delegates - enough to pass the Republican threshold of 1,276.
Meanwhile, Democratic primaries in these states are widely expected to serve up another victory to former Vice President Joe Biden who is competing with Senator Bernie Sanders for the party's nomination.
To win the Democratic party nomination on the first ballot 1,191 delegates are needed. Biden so far has won 896 delegates to Sanders’ 699 after more than 25 primary contests, according to a Washington Post official delegate count.
