President Barack Obama's strongest supporters in the United States are at the lowest level of his presidency yet and support from liberals is also sharply down from earlier this month, according to a daily presidential tracking poll.

The percentage of people that 'Strongly Approve' of President Barack Obama was 19 percent, according to Rasmussen reports. That figure is down from an April high of 27 percent on April 2.

Today's numbers reflect the lowest level of Strong Approval yet recorded for this president. There has been a sharp decline in enthusiasm among liberal voters, Rasmussen said.

The number of liberals who Strongly Approve of the president's performance was 37 percent on April 11, down from 63 percent a year ago, 57 percent at the beginning of 2011, and 52 percent a week ago, according to the report.

Events which may have affected voters views include the just concluded negotiations involving Obama and Congress in which a deal to cut $38.5 billion from the federal budget for the rest of the year was reached. Other events include the conflict in Libya, where the U.S. joined France and Britain to attack Libyan air defenses in a bid to protect civilians.

Over the course of his presidency, Obama's Strongly Approve' was highest soon after he came into office on January 20, 2009.

The highest percentage of people that Strongly Approve of the president reached a high of 45 percent on January 23, 2009. His strongly approve support steadily dipped to 28 percent later that year on July 12, 2009.

Also on April 11, the percentage of people that Strongly Disapprove of Obama was 39 percent. The Total Approve percentage was 44 percent and the Total Disapprove percentage was 55 percent.

His highest Total Approve ranking was 65 percent on January 21, 2009. The lowest Total Disapprove ranking was 29 percent on January 23, 2009.
