Here’s what happens when the logos and fonts are switched for the candidates…

“WHAT?! The symbol of hope and change being used for old McCain? He’d be the oldest president ever at 72! 72 years, people! This design is a mockery! A travesty!”

“WHAT?! A military look for two guys with no military experience? The last time a major party nominated a ticket with no military experience was 68 years ago! 68 years, people! This design is a mockery! A travesty!”

Original sign as pulled from here. The serif font seems to be a stroked version of Requiem while the sans serif is Gotham. A designer ponders the Obama name font switch from Perpetua upper and lower case to Requiem small caps. More design observations here.

Original sign as pulled from here. The font is Optima Black, known for having “sorta” serifs. The star symbol appears to be from Wingdings 2. Placing the McCain lockup on packaging. More design observations here, including the observation that Optima is used on the Vietnam Veterans Memorial in Washington, D.C.—furthering the connection to McCain.
