I think the similarities are strong. When national security was the big issue (historically a weak issue for the Dems), the Dems put forward a politician with a decorated military career and tried to put the focus on that rather then his political service. The GOP responded by focusing attacks on that same military service, ostensibly Kerry’s strong point.
Now the economy is the big issue (historically a weak issue for the GOP), the GOP puts forward a “safe” candidate with a successful business career and have tried to put focus on that rather then his political service. The Dems are responding by attacking that same business career.
But of course, the difference is as bricker said. The swiftboat stuff was false. I don’t really agree with much of the negative spin Obama puts on Romney’s time at Bain, but I haven’t seen him approach the kind of falsehoods that were part of the Swiftboat thing.
Romney and Kerry are reminiscent of each other in a lot of ways, actually. (hopefully a new similarity will be added in the fall).
