Reuters Boston staff photographer Brian Snyder is traveling with Republican U.S. presidential nominee John McCain through election day November 4. He and his colleague Jason Reed traveling with the Obama campaign are posting daily blog entries sharing their experiences and favorite pictures of the day from their campaign coverage.

One of the very first frames that I exposed on the McCain campaign this morning also turned out to be one of my favorites of the day. The Defiance, Ohio high school band lined up for Senator McCain’s entrance for his first early morning campaign rally of the day and showed more than a little enthusiasm.

However, later in the day, good old “Joe the Plumber” himself was trotted out to actually join Senator McCain on the campaign trail and lend his support and those images will surely totally overshadow the ones that we made earlier.

Bill Clinton finally stands on the same stage with and endorses Barack Obama in the flesh - just days before election day.

Once a political foe of Barack Obama as the former president actively and energetically embraced the presidential primary campaign of his wife, Hillary Clinton, it was only a matter of time before former President Bill Clinton had to rally in person behind the Democratic party’s presidential nominee, Barack Obama.

The occasion finally came at a campaign rally in the ironically-named Florida town of Kissimee on Wednesday night. Throwing his full support behind Barack Obama, Bill Clinton appeared on stage with the Illinois senator and gave a rousing speech in his endorsement of the man who may become the first African-American president in U.S. history.

I would love to know what Obama was whispering into the ear of the former president as the rally wrapped up and they waved to the thousands that had gathered. As the rally drew to a close I tried to plot the best location to capture the final moments of the pair on stage together, and took a gamble to go to the back of the stage and do the reverse angle. When Obama leaned back and whispered something into Clinton’s ear, I knew it was something different that the cameras at the front of the stage may not have captured. It was striking to see the most recent Democratic president and the potential next one on stage together as the final push for the U.S. presidential election escalates, with election day just days away.
