Presumptive Democratic nominee Joe Biden’s lead over President Donald Trump now stands at five points, but Trump has an edge in the critical battleground states that could decide the electoral college, according to a new CNN poll conducted by SSRS.

In the new poll, 51% of registered voters nationwide back Biden, while 46% say they prefer Trump. Partisans are deeply entrenched in their corners, with 95% of Democrats behind Biden and the same share of Republicans behind Trump. The two are close among independents (50% back Trump, 46% Biden, not a large enough difference to be considered a lead), but Biden’s edge currently rests on the larger share of voters who identify as Democrats.
