Voting absenteeism: McCain vs. Obama who missed more votes?

Question

Does this matter? If not, why not?

60% is A LOT more than 40%

John McCain: Missed 374 votes (61.8% of total)

Barack Obama: Missed 263 votes (43.5% of total)

Answer 1

But what happens when you factor in Obamas "present" votes?

Answer 2

I didn't know that.  Thanks.

Answer 3

I think it more of a point of which has done more damage with the legislation that he supported, wrote, and voted on.
