A Public Policy Polling (PPP) survey shows Clinton as the democrats' leader with 42 percent of voters' support, with a big gap compared to the 24 percent obtained by senator Bernie Sanders.
However, the campaign of the democrats' favorite has now its biggest challenge in the potential entrance to the race of vice president Joseph Biden, who according to PPP has the support of 20 percent of voters despite it is not still decided his participation in the battle.
Hillary saw her 50 percent of support reduced before launching her candidacy chiefly due to the Republicans' attacks for her performance as secretary of State during the attack to the US consulate in Bengasi, Libya, and her management of emails in a private sever when she was holding that post.
Media analysis refer that Republicans made their goal of decreasing the favoritism of the ex first lady, because the same PPP poll placed Clinton with 55 percent of support in August.
On the other hand, a poll of the University of Quinnipiac revealed on Wednesday that both Clinton and Trump continue leading their parties in three key states (Florida, Pennsylvania, and Ohio) despite Republican Ben Carson and vice president Biden emerge as the most successful candidates to general elections in those places.
