Is Biden Untouchable?

Is Joe Biden telfon?
According to Politico, he might be.
None of the recent controversies seem to have had any effect on his candidacy.
Biden remains the front-runner in national polls and in the four early states.
A new POLITICO/Morning Consult poll shows his most recent controversy isn’t hurting Biden in any significant way.
Biden made waves when he said talked about working with multiple segregationists.
41 percent of likely primary voters said the remarks would make no difference to them.
29 percent said they would be more likely to vote for him.
Just 18 percent said they would be less likely to vote for him.
The numbers were about the same for black voters.
30 percent said they would be more likely to vote for Biden, 20 percent said less likely and 27 percent said it made no difference.
