I agree with TUMe that Biden is a superior candidate to that dishonest, lieberal and probable lawbreaker Hillary and he is a bigger threat to the GOP if he gets in the race. But this comes down to who the Reps run IMO. They are stigmatized with the tag of the old, rich, white and spoiled party - which really isn't them, but the public by and large believe is the case because of media bias. IMO that is why the Reps must have a transformative candidate like Rubio at this point. Someone who has the values of the party, but not the "look". It would be strange for the dems who have spent years playing the race, gender, ethnic and "age"card to have to explain away a candidate their party should accept, but can't because of "political" differences. In effect, they would become the victim of their own propaganda.
IMO
