Primaries in the USA: Trump and Biden are fighting for the votes of the dissatisfied. Only 42.6 percent of those surveyed have a positive opinion of Trump.

Biden regularly gets confused during appearances, searches for words and mixes up people and places. If the 77-year-old is re-elected again, he would be the oldest politician to ever move into the White House. But Biden has another problem: parts of his own party punished him for his stance on the war in Israel.
