A brewing fight over government funding is giving Senate Minority Leader Chuck Schumer (D-NY) a second chance to stand his ground against Republicans and avoid the divisions that hobbled his party in a similar showdown earlier this year.

On Tuesday, Schumer made the case that the political tides had shifted since March, when he caved to Republicans and handed them the Democratic votes to avoid a government shutdown. The decision prompted backlash from within his party and even calls for him to step aside from leadership, but in this next funding fight, Schumer is signaling he won’t back down.
