Romney is an utterly arrogant leftist who has bought the GOP nomination by paying off many party figures and many issue groups and, in turn, being bought by his Wall Street backers for what nefarious taxpayer-raping schemes we will find out only IF and when Romney is elected. Thinking that we (or even the usual lapdog monarchist GOP senators or congresscritters known as "moderates") will keep "Romney on the straight and narrow" is a delusion on an identical scale to the proverbial flea crawling up the elephant's leg with rape in mind.
What happened at long last to Lugar in Indiana and what MAY happen to that whore Dewhurst in Texas is the ONLY thing that intimidates the rank and file GOP caucus whores in DC. After November, our next scheduled opportunies will be in 2014 just as we won't be having any POTUS election until at least 2016 (and then only if Romney is beaten now and otherwise 2020). If we could not stop Romney's nomination in 2012, we sure as hell will not stop his renomination as an incumbent POTUS. If Romney has two terms, it will become very hard to find anyone who remembers by 2020 that "Republican" EVER meant something different from Demonrat.
I really don't buy the whole "Romney bought the nomination" train of thought. To believe that, you'd have to believe that (a) people who walked into the voting booth and pulled the lever for Romney had absolutely no free will of their own and (b) Romney's people arranged for a large group of real conservatives to run and split the Not Romney vote so that he would sneak in.
Just not buying it.
