(CNN) Poll of the week: A new CNN poll conducted by SSRS released this week finds that President Donald Trump's approval rating among voters stands at 45%. His disapproval rating is at 52%.

This poll was taken during the first week of March, mostly before the coronavirus outbreak began to dominate the news cycle. This poll, therefore, gives us a good baseline to track how Trump's handling of the crisis is affecting how voters view him.

What's the point: The way voters perceive how Trump and his administration are dealing with coronavirus could go a long way towards determining his reelection fate. And we can track that through his approval rating in the coming weeks and months.

Trump's approval rating is the most important datapoint to look at when judging his reelection prospects. Historically, an incumbent's approval rating is highly correlated with his reelection odds. Even at this point from an election, presidents' approval ratings are predictive of whether or not they're reelected.

As it stands, an approval rating of 45% among voters on Election Day 2020 will likely not be good enough for Trump to win. One estimate from FiveThirtyEight's Nate Silver gave a president about a 3 in 10 shot of winning with an approval rating of 45%. That, of course, would still give Trump a chance if the election were held today.
