Mary Lou McDonald is almost as popular as the Taoiseach Leo Varadkar, according to a new poll.
A Behaviour and Attitudes poll in today's Sunday Times brings a big boost for both Sinn Féin and its new leader.
Support for Fine Gael is up one point to 33%, eight points clear of Fianna Fáil who have dropped two points to 25%.
The Greens and Solidarity/PBP are unchanged on 2% and 1% respectively.
The Independent Alliance is down one point to 2%, while the Social Democrats move up to 1%.
Renua also have 1% support, while Independents and others are down two points to 10%.
"This month's poll sees Sinn Féin broach the 20% mark for the first time in more than a year," said Sunday Times political editor Stephen O'Brien.
"They're up two points to 21%, they were up three points from 16% to 19% last month... and Mary Lou McDonald's personal satisfaction rating as leader of Sinn Féin is up five points in a single month to 51%."
