Rationality has absolutely nothing to do with voting for trash like Romney. Conservatives absolutely REFUSE to vote for Robozombie or for Obozo: for precisely the same reasons. To make believe that there are meaningful differences between the two of them is what violates both rationality and integrity.
Indeed.
In fact, we need to consider, given how much Romney and Obama are alike, whether having Romney in the White House with a Republican Congress might not actually be more dangerous than Obama with a GOP Congress.
After all, the Republicans will at least make an effort to stand up to Obama. Despite all that he's done, it would be a LOT worse had he continued to have a Democrat Congress.
However, there is a strong possibility that with Romney in office, the GOP would go along with him on any spending, bad judicial nominations, etc., since he's "their" guy, and we wouldn't want a Republican Congress embarassing a Republican President, now would we? It would be like George W. Bush with his prescription drug plan, No Child Left Behind, and the rest all over again, except magnified, since Romney's instincts are so much further to the Left than Bush's were. And we wouldn't even get any social conservative bones thrown our way with Romney.
It may actually be less dangerous in the long run to have a guy who the Republicans in Congress will actually fight than a guy who they will go along with almost all of the time.
As such, while we need to work hard to elect as many (conservative) GOPers at the congressional and Senatorial level, working for Romney really isn't such a high priority. He lied, cheated, and stole his way to the nomination. Fine. Let him have his turn being the footnote on Wikipedia. Maybe after foisting off and then losing with a GOP-E RINO candidate for, what, the fourth, fifth time now, the GOP-E will finally be discredited, and can be replaced by people with the country's best interests at heart, instead of their own personal power and advancement.
