Difficult to say. Brazilian politics has been in a state of crisis for some time now, in part fuelled by the country's largest-ever corruption investigation.
Known as Operation Car Wash, the inquiry - which started in March 2014 - has implicated some of Brazil's biggest names, and a third of the cabinet are under investigation for corruption.
Then last month, leaked audio recordings surfaced that seemed to show Mr Temer encouraging the payment of hush money to Eduardo Cunha, the former lower house speaker who led the impeachment process against Ms Rousseff.
The recording led to calls for Mr Temer to step down, but he has refused to go, despite being abandoned by some allies and powerful media outlets.
The president is very unpopular, with approval ratings in the single digits. But among the political and business elite he was tolerated, partly because he was trying to push through pension and labour reforms which, they say, were vital to revive the country's economy.
Brazil finally emerged out of recession in the first quarter of this year, after two years of negative growth, and Mr Temer said he was the only one capable of bringing the stability needed for full economic recovery.
President Temer is being investigated for other allegations of corruption.
If he were to be charged, then that is where the political calculations come in.
According to the Brazilian constitution, if there are fewer than two years left in a term, Congress will choose a caretaker president to govern until the next elections, due in 2018.
But nobody really knows the rules of this kind of election because it has never happened before. That would likely bring further uncertainty, analysts said.
Many want direct elections so they can choose a new leader rather than have it chosen by a Congress that is seen as part of the problem.
This, however, is unlikely to happen, and not only because of the current legislation: some of the biggest parties oppose to an election now as many of their top names have been implicated in the investigations and, with increasing public anger, they would probably suffer big losses.
