I am not educated enough to judge on her willingness and ability to follow through with her economic policies. But it looks like she might no even make it to the final voting round. See this recent poll for the next voting round with three remaining candidates to vote for. I guess it is close but imho Massa has no chance of winning the final round if either of the two other candidates endorse each other if they should lose the next voting round. Massa can only realistically win if Bullrich endorses him. And even that might not be enough.

"Economic Minister Sergio Massa leads in Argentina’s upcoming presidential race. He has 30.7% of the projected first-round votes.

President Alberto Fernández supports Massa. His opponent, Javier Milei, follows closely with 27.9%. Both are statistically tied within the survey’s margin of error.

The first voting round is set for October 22. An online survey gathered these numbers. It involved 3,778 participants and ran from September 10 to 20.

The study has a 95% confidence level and a 2-point margin of error.

Patricia Bullrich, a center-right candidate, also shows promise. She holds 27.7% of voter intent."
