CNN said Thursday a CNN/Opinion Research Corporation survey found 55 percent of the 1,010 adult U.S. residents polled stated they have unfavorable views of Cheney, who has become an outspoken critic of U.S. President Barack Obama's administration.
But the poll conducted May 14-17 did find that the percentage of people with a favorable impression of the former vice president has increased.
The poll, which has a margin of error of 3 percent, found 37 percent of respondents had a positive position in regards to Cheney. That percentage marked an 8 percent increase from the results of a January poll regarding the Republican official, CNN said.
"Is Cheney's uptick due to his visibility as one of the most outspoken critics of the Obama administration? Almost certainly not," CNN Polling Director Keating Holland asked. "Former President George W. Bush's favorable rating rose six points in that same time period, and Bush has not given a single public speech since he left office."
