(CNN) The Democratic race for president has, at least for now, been reset. We had two high quality national polls released on Tuesday from CNN and Quinnipiac University, and they show two very similar trends:

The current top tier is former Vice President Joe Biden and Joe Biden alone after his announcement last Thursday. There is a second tier of candidates that has a number of candidates in it including a declining Sen. Bernie Sanders and slowly rising Sen. Elizabeth Warren.

Biden scored 39% in our CNN poll and 38% in the Quinnipiac poll. Compared to the March polls from those outlets, Biden's up 11 and 9 points respectively. That's a clear indication of an announcement bump, which could dissipate with time.

Still, Biden entered the race with near universal name recognition and some bad press. With that in mind, it's noteworthy that Biden even got a bump. Biden is about 25 points ahead of the competition in both the CNN and Quinnipiac polls. This lead could fade, but it's tough to argue with the idea that Democratic voters are at the very least interested in what he's selling.

Democrats for now seem far less interested in what Sanders is offering. He dropped from 19% to 15% in CNN's poll and 19% to 11% in Quinnipiac's. He maintained second place in the CNN poll, though he placed in third place in the Quinnipiac poll behind Warren.
