The announcement of Joe Biden's reelection campaign might come within the next 48 hours. However, over 3 out of 4 Americans are rooting for a last-minute change of heart on his part. In a new NBC News survey released on Sunday, just 26% of Americans support Biden's bid for a second term, while 70% of Americans oppose it. Age is cited as a factor by 69 percent of those opposed to the 80-year-old president seeking reelection, with 48 percent describing it as a "major" one.
