How do you think the lawsuits get dismissed, for whatever reason? Do you think judges sit at a desk, review the day’s stack of complaints, and rubber stamp them “meritorious” or “frivolous”?
What do any lawsuit filed against Bush or the amount of time Bush (or Obama) spent in court have to do with this? This issue is legal fees associated with defending lawsuits.
You obviously have no clue of legal procedure.
Obama has not had to defend himself in a single lawsuit. It's very simple.
In real life or in birther fantasyland where legal procedure seems to be invented on the spot and is found nowhere in established constitutional law?
