The calculations of America's presidential election map are shaken by the start of Florida Governor Ron DeSantis' campaign. The tremor is not limited within his Republican Party and former President Donald Trump's campaign, but also extends to the camp of Democratic President Joe Biden.

Democrats prefer to confront Trump, who is only two years younger than Biden. For Democrats, Trump represents an easier confrontation than De Santis, who does not carry a legacy of 4 years in the House of Representatives."We all running against Trump, but we hate him equally," Biden aide says.
