It's no accident that Mitt Romney has done so well during this election cycle. He has excellent name recognition, he's extremely well organized, he's a great fundraiser, he's become a polished debater, and he's not gaffe prone. His business experience doesn't hurt either, although it is worth noting that the only reason he's able to brag that he's not a "career politician" is because he lost to Ted Kennedy for the Senate and probably would have lost in 2008 had he run for governor of Massachusetts again.
All that being said, there's a reason why Mitt Romney has been unable to walk away with the nomination despite all of those advantages. It's because Mitt is a deeply flawed candidate. Yes, he would certainly be better than Obama (and I will vote for him if he gets the nomination), but this IS NOT someone conservatives should want as their nominee.
1) Romneycare: One of the biggest issues the Republican Party has to run on in 2012 is Obamacare. Although Mitt Romney does oppose Obamacare, it's purely a political calculation because he still supports Romneycare in Massachussetts. Sure, there are a few differences, but it's also fair to say that Obamacare is just Romneycare on a larger level. Even Mitt's consultants on Romneycare, like Jonathan Gruber, have admitted that Obamacare is just Romneycare writ large,
The truth is that the Affordable Care Act is essentially based on what we accomplished in Massachusetts. It’s the same basic structure applied nationally.
In 2008, when Romneycare was still in its infancy, Romney might have been able to sell his experience with healthcare as a plus to the American people. However, we now know that his signature issue has been a miserable failure that has increased insurance rates in Massachusetts to the highest level in the whole country. Moreover, are the American people going to buy that the GOP's opposition to Obamacare is anything more than politics as usual if we have a nominee who still supports "Obamacare 1.0?" Can we even trust Mitt to really fight Obamacare since he obviously supports the basic principles behind it?
