Harris Asked to Lead on Voting Rights. She Has Her Work Cut Out for Her.

Her new role comes as the Senate enters a crucial month in the Democratic drive to enact the most extensive elections overhaul in a generation.

WASHINGTON — Vice President Kamala Harris did not come to her role with a list of demands. She wanted to be a generalist, in large part to learn the political rhythms of a president she was still getting to know. In the first few months of her tenure, some of her portfolio assignments were just that: assignments. But on the matter of protecting voting rights, an issue critically important to President Biden’s legacy, Ms. Harris took a rare step. In a meeting with the president over a month ago, she told him that she wanted to take the lead on the issue. Mr. Biden agreed, two people familiar with the discussions said, and his advisers decided to time the announcement of Ms. Harris’s new role to a speech he delivered on Tuesday in Tulsa, Okla. In his remarks, the president declared the efforts of Republican-led statehouses around the country to make it harder to vote as an “assault on our democracy, ” and said Ms. Harris could help lead the charge against them.
