There are 2 issues. Political belief and criminality. Obama is wrong on both counts. Romney OK on one (criminality), possibly might be OK another. Obama is not only a hardcore leftist, he is a criminal. He ignores Congress at will and oversteps his prescribed lawful duties frequently. He is an exceptional danger to America because he is both a criminal willing to ignore the Constitution in novel ways and an extreme leftist.
I see little difference between the two. Romney will do virtually the same thing as Obama in terms of record, he’ll just have the full support of the GOP who will make excuses for him, unlike Obama has now.
Plus, all the criminality you cite Obama as having done - neither Romney nor the GOP is going to demand or exact justice for the violations of the rule of law committed by this regime. I fully expect they are simply going to consider what Obama did as PRECEDENT for what Romney and the Ruling Class can now do for themselves, if by some incredible miracle, enough Americans overcome the largest fraud ever perpetrated during an election to allow Romney to take an oath of office in January.
A liberal Democrat versus a Marxist - how far Left America has fallen is just the symptom of the cultural and spiritual evil this nation has fallen into.
