As far as we know, Liddy is all talk, he never actually attempted to bomb anything. We don't even know that he ever really wanted to, he could have just made that up to help sell his book and make himself look like a badass.
OTOH, we know for a fact that Ayers and the other Weathermen actually did plant bombs intended to kill people.
Those who cited Palin's selection as a factor in their vote (60% of all voters) favored McCain by 56% to 43%.
But according to the people who linked Ayers to Obama its the same level of connection doesn't matter what he did only matters that there is the connection. Obama-Ayers has a similar level of connection as Liddy-McCain only difference Liddy actually went to Jail. And i don't believe he ever apologized for watergate or the other things he was planning on doing to essentially get rid of the opposition to the republican party.
And 60% of all voters said Palin was a factor does it give the percentage of how many were democrats and how many were republicans? For it to be that wide i guarantee you at least 50% percent of that 60% were people who were voting republican no matter what and just answered that yes Palin further enforced that decision. Also that's 60% of all voters polled not all voters because you have to remember there's a good percentage of people who vote absentee like myself and a lot of people like my parents who avoid the pollsters. Also they didn't ask that question in predominately Democratic states like Massachusetts and Vermont. And also that number could again be skewed because there were a good portion of people who despite Palin's incompetence still voted McCain.
