A Romney ad that goes too far

MItt Romney’s latest ad argues that John McCain and Hillary Clinton are “very close” (the phrase comes from Bill Clinton). The ad cites several issues — e.g., amnesty for illegal aliens and the Bush tax cuts — on which the postions of McCain and Hillary were very close.
The ad also cites “blocking conservative judges.” Yet, McCain did not agree with Clinton on this issue. McCain was part of The Gang of 14; Clinton was not. McCain voted to confirm John Roberts and Sam Alito; Clinton did not.
McCain did, I believe, help block Jim Haynes from becoming a conservative judge. But overall, he is not close to Clinton when it comes to either the circumstances under which judges should be blocked (i.e., filibustered) or propensity to support conservative judicial nominees.
