(THE WEEK) -- Sen. Elizabeth Warren (D-Mass.) is going nowhere but up.
The 2020 candidate pulled off a rare showing in an Economist/YouGov poll published Wednesday, tying the largely untouchable former Vice President Joe Biden with 26 percent support among registered voters. It marks one of the few polls where Biden is within danger of losing his frontrunner status, and contains a dismal prediction for Sen. Bernie Sanders (I-Vt.).

Biden has only had a few close calls in previous polls, but Warren's 2020 rise has seemingly been eating away at his support as well as Sanders'. In a late August poll from Monmouth University, Sanders and Warren topped the pool with 20 percent support, and Biden was just behind at 19 percent. In this Economist/YouGov poll, Biden is back up, but so is Warren, both leaving Sanders a full 10 points behind at 16 percent.
