How did Cleopatra influence events in Rome?

Cleopatra was the focal point of Roman hatred and this was due largely by the Propaganda war between Antony and Octavian. However Cleopatra herself added to her own negative image among the Romans by things she supposedly said and the accepting of the Roman territories at the Donations of Alexandria. Her political alliance with Antony as well as her personal one also helped to stir resentment and hatred towards her. Even Antony's strongest supporters urged him to drop her and return to Rome, which he refused to do. It was not difficult for Octavian to have the senate declare war against her.
