You neglect that a (lot) will happen in the next four years.
A lot.
Several supreme court judges will retire. Four budgets are to be approved.
War may break out.
It is far too important a time to have Obama screwing things up for four more years.
No question. Romney / Ryan 2012.
Who in 2016 may be another question entirely. But for now Romney / Ryan.
No question.
Voting for him does encourage the GOP-e to continue running liberal candidates and then laugh at all the voters that vote for them because there are no conservatives on the ticket.
And, BTW Romney has a horrible record on appointing judges, seems to prefer leftist democrats.
