There have been significant changes in the perception of Republic presidential candidate John McCain in the two days of polling since he named Alaska Governor Sarah Palin as his running mate, according to Rasmussen Reports. 49 percent of Republicans now voice a "very favorable" opinion of McCain – up six percentage points from 43% just before the announcement.
Also, 64% of unaffiliated voters now give positive reviews to the Arizona senator, up ten points since naming his running mate.
Barack Obama is ahead of McCain by three percentage points – exactly the same edge Obama enjoyed a week ago on the eve of the Democratic National Convention.
