they are very good at getting job using various means. another reason is most people may think the economy is not such bad because it has been pumped by printed money.
by the way, republican tradition is next in line: McCain lost to Bush in 2000 and run again in 2008. same for Romney. Democrats are swim or sink. i still believe romney is a decent guy and could do a better job working with congress to get things done.
now the election is over, hope obama will have a successful second term.
