A recent independent survey of 1,000 likely American voters showed almost half believe it's negative to compare candidates to Obama or George w. Bush.
The survey showed:
47 percent consider it a negative to describe a candidate as being like Barack Obama, while 48 percent view a comparison to George W. Bush as a negative.
For 29 percent comparing a political candidate to Obama is a positive, while 19 percent consider it somewhere in between a positive and a negative.
24 percent say describing a candidate as being like Bush is a positive, while 26 percent think it's somewhere in between.
In January 2009, as Bush left office, 57 percent of Americans described him as one of the five worst presidents in U.S. history, but by November 2010, 53 percent of voters rated him somewhere between one of the best and one of the worst.
52 percent of voters believe that describing a candidate as being like Reagan is a positive, while 25 percent view that as a negative description and 19 percent rate it as somewhere in between.
51 percent said comparing a candidate to Reagan was a positive in late August 2011, but that was the first time in surveys for several years that a majority of voters felt that way.
Still, it's always been best as far as voters are concerned to compare a candidate to the Republican who served in the White House from 1981 to 1989.
41 percent consider it a positive to compare a candidate to Bill Clinton, while 31 percent say it's a negative and 26 percent say it's somewhere in between the two.
38 percent said in October 2011 that it was a positive to describe a political candidate as being like Clinton, but 24 percent saw that description as a negative, and 35 percent put it somewhere in between.
