The Battle for the Democratic Nomination

Hillary is making a strong comeback due to Obama's pastor. Talk radio is actually helping Hillary and I think they are smart enough to know that Barack would be a weaker opponent than Hillary for the general election especially considering the latest revelation just mentioned. Yet, conservatives continue to attack and strengthen Hillary. Rush Limbaugh says he wants the Democrats to continue their in-house fight so it will help the Republicans. When has Rush been willing thus far in the primaries to help McCain? I am very suspicious that they intend on helping Hillary on purpose.
A couple weeks ago, it was common thought that Obama had it locked up and Hillary was going to crash and burn. One would speculate that at any time something unsavory would occur because too many forces are not pleased with this development. As with many dirty tactics, once they are initiated they may take time to have an effect. These tactics may unfold when they are no longer needed. Furthermore, if these tactics are fleshed out, it can reverse the damage. This is going on right now as we have just learned that Obama's passport records were breached by State Dept employees obviously bought out to give the info to another party to hurt Obama. This action only makes Obama supporters more passionate in the fight.
Why are the conservatives helping Hillary? Rupert Murdoch owns Fox News and Rupert has donated substantially to Hillary's campaign. This is surprising since Fox News is villified by many for being too conservative slanted and not "fair and balanced" as they proclaim. I actually liked Fox News for many years but I've graduated to a new level of understanding politics. Investigative reporting is rare these days and the spoon fed news is too programmed and controlled. Why is Hillary getting support from the right? Perhaps some Republicans have bought into globalism and are throwing true conservatism and the US Constitution under the bus.
