I honestly think one of two things has to happen for the ban to lift:


1) Castro dies


2) a democrat gets in the White House.


Not saying anything about Bush as a President,however we were very close to getting the ban lifted recently after both the House and Senate had been presented a bill doing so. Then, when Cuba was up for the Humanitarian award last year, the US delegates walked out of the UN and Bush went out of his way to state that we would never have a relationship with Castro, and so on. Looks like something will have to change in one of the two administrations.
