Romney is running an embarrassment of a general election campaign. This could easily be because he is transitioning from a primary campaign to a general election campaign. Eight years ago (give or take) John Kerry had the same problem and he was never able to get out primary campaign mode. The major difference between Kerry and Romney (and it is not their hair or strong dedication to their political philosophy) is that Kerry, as a Democrat, could rely on some trusted demographic groups such as African-Americans, women and Hispanics. These are not groups that Tricky Mitt can count on and thus a year long primary mode campaign will lead to him losing poorly.
If things continue as now in the Romney Camp I envision:
Obama/Biden (D): 344 EVRomney/Portman (R): 194 EV So I guess I would vote for the first option. I also must add that I am not very good at political predictions so the Romney folks should be very happy I expect a terrible defeat for their man.
